Pakistanis Join Hunt for "God Particle"


Humans have been engaged in the perennial effort to crack the code of the physical world; to figure out what the universe is made of; to know the origins of human and other species; in other words, to get to the very bottom of things. These are existential questions that religions and philosophers have offered answers to. But most scientists remain unconvinced with these answers and continue their hunt for "God Particle".

The most high-profile effort to find "God Particle" is taking place about 300 ft below ground in a tunnel at the French-Swiss border. Buried there is a massive particle accelerator and super collider called LHC (Large Hadron Collider) run by the Swiss lab CERN (European Organization of Nuclear Research), which has two beams of particles racing at nearly the speed of light in opposite directions and the resulting particles produced from collisions are being detected by massive detectors in the hope of experimentally finding the fundamental particle of which everything in the universe is built from: God Particle. The knowledge gained from this multibillion-dollar atom smasher may eventually help scientists treat diseases, improve the Internet, and open doors to travel through extra dimensions, according to the scientists associated with it.

Among the world scientists working at CERN on LHC project is Professor Hafeez Hoorani of Pakistan's Quaid-e-Azam University in Islamabad. He is one of 27 Pakistani scientists at CERN.CERN is the most highly respected research lab in Switzerland responsible for LHC. He acknowledges that Pakistan government's support for Pakistani scientists' serious involvement at CERN materialized only after 1999, the year former President Musharraf's government assumed power. He also gives credit to Dr. Abdus Salam, Pakistan's only Nobel Laureate, for inspiring him and his colleagues to pursue serious scientific research. Here's what Professor Hoorani says about Pakistan's involvement in LHC and CERN:

When I first came to CERN, I was mainly working on technical things but became increasingly involved in political issues. In 1999, I went back to Pakistan to set up a group working on different aspects of the LHC project. There I had to convince my people and my government to collaborate with CERN, which was rather difficult, since nobody associated science with Switzerland. It is known as a place for tourism, for its watches, and nice places to visit.

However, Pakistan already had an early connection to CERN through the late Abdus Salam, the sole Nobel laureate from Pakistan in science and one of the fathers of the electroweak theory. CERN has been known to the scientific community of Pakistan since 1973 through the discovery of neutral currents which eventually led to the Nobel Prize for Salam. We are contributing much more now because of the students who worked with Salam, who know his theories and CERN, and who are now placed at highly influential positions within the government of Pakistan. They have helped and pushed Pakistan towards a very meaningful scientific collaboration with CERN. People now know that there is an organization called CERN. It took a long time to explain what CERN is about, and I brought many people here to show them, because they did not imagine CERN this way. Many people support us now which gives us hope…”



In addition to the 27 scientists, Pakistan has made material contributions to the tune of $10m. According to a post by Ujmi on WTF, Pakistan signed an agreement with CERN which doubled the Pakistani contribution from one to two million Swiss francs. And with this new agreement Pakistan started construction of the resistive plate chambers required for the CMS muon system. While more recently, a protocol has been signed enhancing Pakistan’s total contribution to the LHC program to $10 million.

CERN is a pan-European effort and all of its member states are European. Pakistan, with all of its contributions to LHC project, is hoping to join the ranks of India, Israel, Japan, Russia, Turkey and United States as an observer state at CERN.

Pakistan has contributed the LHC in numerous ways including some of the following in particular:

1. Detector construction
2. Detector simulation
3. Physics analysis
4. Grid computing
5. Computational software development
6. Manufacturing of mechanical equipment
7. Alignment of the CMS (Compact Muon Solenoid) tracker using lasers
8. Testing of electronic equipment
9. Barrel Yoke: 35 Ton each feet made in Pakistan
10. Assembly of CF (Carbon Fiber) Fins for the Silicon Tracker’s TOB (Tracker Outer Barrel).
11. 245 of the 300 CMS chambers required were made in Islamabad, of which 226 are already installed at CERN.

The Higgs boson, also known as "God Particle", is a hypothetical massive scalar elementary particle predicted to exist by the Standard Model of particle physics. It is the only Standard Model particle not yet experimentally observed. An experimental observation of it would help to explain how otherwise massless elementary particles cause matter to have mass. More specifically, the Higgs boson would explain the difference between the massless photon and the relatively massive W and Z bosons. Elementary particle masses, and the differences between electromagnetism (caused by the photon) and the weak force (caused by the W and Z bosons), are critical to many aspects of the structure of microscopic (and hence macroscopic) matter; thus, if it exists, the Higgs boson is an integral and pervasive component of the material world.

The Standard Model of particle physics has its limits. It can't explain several big mysteries about the universe that have their roots in the minuscule world of particles and forces. If there's one truly extraordinary concept to emerge from the past century of inquiry, it's that the cosmos we see was once smaller than an atom. This is why particle physicists talk about cosmology and cosmologists talk about particle physics: Our existence, our entire universe, emerged from things that happened at the smallest imaginable scale. The big bang theory tells us that the known universe once had no dimensions at all—no up or down, no left or right, no passage of time, and laws of physics beyond our vision.

There have been many other efforts to build particle accelerators and supercolliders including SLAC (Stanford Linear Accelerator) and Fermi Collider, but none so ambitious and massive as the LHC. It is a commendable effort that will advance human knowledge. However, there is no guarantee that it will help find "God Particle".

This surely is an extremely informative post and a heartening one too. Being a part of the domain of science and technology, I certainly feel proud of the sort of contribution our country is making in this historic experiment.

The important thing is to stay involved in leading research and business activities with other more developed nations. Results will surely and eventually come, regardless of whether we live to see them or not. The seeds must be sown NOW.
In spite of the ineptitude of our political leadership and rampant corruption in our nation, Pakistanis seem to find a way to get involved in all kinds of research and science from Antarctica to Switzerland to North Pole. Many have started successful high-tech companies in US that have gone public.

Here is a recent Dawn report of international recognition of Pakistani woman scientist:

KARACHI: Pakistani Scholar Dr. Hina Siddiqui won the best “Oral Presentation Award” in the 11th Eurasia conference on Chemical Sciences. The international conference was held in Jordon from Oct.6 to Oct.10, 2010.



Dr. Siddiqui’s presentation was declared as one of the top three oral presentations in the conference, where a panel of experts decided upon the top three finalists. Another scholar from Peshawar also got prize in the event, where over 200 scientists delivered their presentations from 69 countries.

Eurasia Chemical Sciences conference was launched by three chemists in 1988 to foster network and knowledge sharing among the researchers of North and South.

Dr. Siddiqui is a PhD in organic chemistry and currently working as research officer at International Center for Chemical and Biological Sciences (ICCBS) at Karachi University.

When she was in school, she read an inspiring interview of Prof. Dr. Atta-ur-Rahman from Hussain Ebrahim Jamal (HEJ) Research Institute of Chemistry, University of Karachi, published in a well-known Urdu science magazine named Amali Science.

In that Dr. Atta-ur-Rehman said institutions are not made up from bricks and stones rather they are made up of people who have dreams and vision.

The sentence changed Siddiqui’s vision and she devoted herself to exploring the unknown. In 2005, she joined HEJ and started her Ph. D under supervision of Prof. Dr. Mohammad Iqbal Choudhary, during her Ph.D Studies she worked on the anti-oxidant properties of various chemical constituents, also she got UBF (Umear Basha Foundation) scholarship and went to University of Kansas for one year to excel in Organic synthesis research.

In the Eurasia conference, a shield and certificate was presented to Siddiqui and the organisers also waived the registration fee of upcoming 12 Eurasia Conference on Chemical Sciences which will be held in Greece in 2012.

Siddiqui told Dawn.com that it is not her prize but it is HEJ award because in HEJ every student gets a world class education and training to excel anywhere in the world.

Siddiqui said that HEJ is a great place to shine, because it is an equal opportunity institute where merit is the only criteria rather than gender discrimination. She urged the females to consider research as their career and vows to continue research and development in the future.

Anon: "Tell me which components has Pakistan made for CERN?"

Here's a post on CERN website regarding Pakistan's contribution to various CERN projects:

Co-operation with Pakistan was pioneered by CMS, and has expanded continuously over the past 15 years to include ALICE and ATLAS as well as to the accelerator sector (SPL (Linac4) and CLIC), making Pakistan a significant partner for CERN. For CMS, Pakistan built the Magnet feet, contributed to the Tracker alignment, and built and installed 320 Resistive Plate Chambers (RPC), as well as contributing to CMS computing, the WLCG and data analysis. Pakistan has also built various mechanical components for ATLAS and for the LHC.

Co-operation with the Pakistan Institute of Nuclear Science and Technology Nuclear Engineering Division (PINSTECH) in the area of radioprotection is being organized. Several high-level Pakistani officials have visited CERN, including President Musharraf in January 2006.

Discussions are on-going with Commission on Science and Technology for sustainable development (COMSATS) for the setting up of a version of the CERN physics teachers programme in Islamabad.

Agreements have been signed covering Pakistani contributions to LHC commissioning and Linac4.

Could you please write something about the God Particle from CERN?

Is the Science entering God’s territory now, a job man wanted to do from ages and always failed?

A sub atomic particle 60 Nano seconds faster than Light, turns Einstein in his grave, and makes time travel possible.

Or you will say it just proves that science was always wrong.

Here's an AP report on CERN's new find:

GENEVA -- A pillar of physics -- that nothing can go faster than the speed of light -- appears to be smashed by an oddball subatomic particle that has apparently made a giant end run around Albert Einstein's theories.

Scientists at the world's largest physics lab said Thursday they have clocked neutrinos traveling faster than light. That's something that according to Einstein's 1905 special theory of relativity -- the famous E (equals) mc2 equation -- just doesn't happen.

"The feeling that most people have is this can't be right, this can't be real," said James Gillies, a spokesman for the European Organization for Nuclear Research. The organization, known as CERN, hosted part of the experiment, which is unrelated to the massive $10 billion Large Hadron Collider also located at the site.

Gillies told The Associated Press that the readings have so astounded researchers that they are asking others to independently verify the measurements before claiming an actual discovery.

"They are inviting the broader physics community to look at what they've done and really scrutinize it in great detail, and ideally for someone elsewhere in the world to repeat the measurements," he said Thursday.

Scientists at the competing Fermilab in Chicago have promised to start such work immediately.

"It's a shock," said Fermilab head theoretician Stephen Parke, who was not part of the research in Geneva. "It's going to cause us problems,

no doubt about that -- if it's true."

The Chicago team had similar faster-than-light results in 2007, but those came with a giant margin of error that undercut its scientific significance.

Other outside scientists expressed skepticism at CERN's claim that the neutrinos -- one of the strangest well-known particles in physics -- were observed smashing past the cosmic speed barrier of 186,282 miles per second (299,792 kilometers per second).

University of Maryland physics department chairman Drew Baden called it "a flying carpet," something that was too fantastic to be believable.

CERN says a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles (730 kilometers) away in Italy traveled 60 nanoseconds faster than the speed of light. Scientists calculated the margin of error at just 10 nanoseconds, making the difference statistically significant. But given the enormous implications of the find, they still spent months checking and rechecking their results to make sure there was no flaws in the experiment.

"We have not found any instrumental effect that could explain the result of the measurement," said Antonio Ereditato, a physicist at the University of Bern, Switzerland, who was involved in the experiment known as OPERA.

The researchers are now looking to the United States and Japan to confirm the results.

A similar neutrino experiment at Fermilab near Chicago would be capable of running the tests, said Stavros Katsanevas, the deputy director of France's National Institute for Nuclear and Particle Physics Research. The institute collaborated with Italy's Gran Sasso National Laboratory for the experiment at CERN.

Katsanevas said help could also come from the T2K experiment in Japan, though that is currently on hold after the country's devastating March 11 earthquake and tsunami.

Scientists agree if the results are confirmed, that it would force a fundamental rethink of the laws of nature.

Einstein's special relativity theory that says energy equals mass times the speed of light squared underlies "pretty much everything in modern physics," said John Ellis, a theoretical physicist at CERN who was not involved in the experiment. "It has worked perfectly up until now."

Though the Higher Education Commission (HEC) has made enormous efforts to promote research work, Pakistan ranked 43rd in the world in terms of published scientific papers in the year 2010, according to Dawn newspaper.

According to the worldwide scientific journal ranking (SJR); Pakistan published 6,987 research documents in 2010. However, the same year United States was on top with 502,804 papers followed by China with 320,800 and United Kingdom with 139,683 research documents. On the other hand, India ranked ninth worldwide.

Among the Islamic countries, Pakistan trailed behind Turkey and Iran which published 30,594 and 27,510 research documents, respectively.

An official of the HEC requesting not to be named told this reporter that in 2007 Pakistan ranked 45th with 3,750 publications, in 2003 it was ranked 50th with 1,539 research papers and in 2000 54th with 1,174 papers. In 1996, the country was on 52nd position with 893 research papers.

The number of publications is directly proportional to the production of PhDs in the country.

“Pakistan gets over $10 billion every year through foreign remittances. On the other hand, due to financial crunch demand for foreign labour has been decreasing worldwide. Even in Saudi Arabia it has been decided to push out foreign labour force and adjust the locals in their places, because it is becoming difficult even for the oil-producing countries to address the problem of unemployment.”

The official claimed that in the West, population was decreasing and the new generation was more interested in the subjects of art and humanities rather than science, mathematics and research work.

Due to this, the official added, the demand for specialised persons would increase in the West and Pakistan can meet the requirement of these nations by producing specialised persons and earn huge foreign exchange.

Sources said most of the successive governments in Pakistan did not take future planning seriously and always tried to solve problems by makeshift arrangements. The government should focus on specialisation in different subjects because only specialised persons can earn foreign exchange to steer out the country from the financial problems.

Executive Director HEC Prof Dr S. Sohail H. Naqvi told Dawn that they had been trying to generate as many specialised persons as possible and for that reason were encouraging and facilitating universities. He said for increasing the number of PhDs, the commission required funds. “Hopefully, Pakistan will further improve its ranking regarding publication of
research papers,” he said.

Here's an ANI report on gene mapping in Pakistan:

Karachi, June 28(ANI): Scientists at the Karachi University have mapped the genome of the first Pakistani man with the help of the Beijing Genomics Institute.

This has made Pakistan the first country in the Muslim world to map the genome of the first Muslim man.

The achievement places Pakistan in the ranks of the few countries- the United States, the United Kingdom, India, China and Japan- that have successfully sequenced the human genome as well.

"Our nation is a mix of a lot of races," said Professor Dr M Iqbal Choudhary, who heads the project. "Pakistanis are like a "melting pot" i.e. a mix of Mughals, Turks, Pashtuns, Afghans, Arabs, etc."

"According to the researchers, the newly sequenced Pakistani genome has uncovered a multitude of Pakistan-specific sites, which can now be used in the design of large-scale studies that are better suited for the Pakistani population," The Express Tribune quoted Dr Choudhary, who is the director of the International Centre for Chemical and Biological Sciences at Karachi University, as saying.

The first Pakistani genome has been mapped using a recently developed technology, ten years after the first human genome was discovered.

Dr Panjwani Centre for Molecular Medicine and Drug Research at the University of Karachi took 10 months to accomplish the task. The individual who has been genetically mapped is a resident of Karachi. (ANI)

Here's a National Geographic report on discovery of Higgs Boson:

..The long-sought particle may complete the standard model of physics by explaining why objects in our universe have mass—and in so doing, why galaxies, planets, and even humans have any right to exist.

"We have a discovery," Heuer said at the seminar. "We have observed a new particle consistent with a Higgs boson."

At the meeting were four theorists who helped develop the Higgs theory in the 1960s, including Peter Higgs himself, who could be seen wiping away tears as the announcement was made.

Although preliminary, the results show a so-called five-sigma of significance, which means that there is only a one in a million chance that the Higgs-like signal the teams observed is a statistical fluke.

"It's a tremendous and exciting time," said physicist Michael Tuts, who works with the ATLAS (A Toroidal LHC Apparatus) Experiment, one of the two Higgs-seeking LHC projects.

The Columbia University physicist had organized a wee-hours gathering of physicists and students in the U.S. to watch the announcement, which took place at 9 a.m., Geneva time.

"This is the payoff. This is what you do it for."

The two LHC teams searching for the Higgs—the other being the CMS (Compact Muon Solenoid) project—did so independently. Neither one knew what the other would present this morning.

"It was interesting that the competing experiment essentially had the same result," said physicist Ryszard Stroynowski, an ATLAS team member based at Southern Methodist University in Dallas. "It provides additional confirmation."

CERN head Heuer called today's announcement a "historic milestone" but cautioned that much work lies ahead as physicists attempt to confirm the newfound particle's identity and further probe its properties.

For example, though the teams are certain the new particle has the proper mass for the predicted Higgs boson, they still need to determine whether it behaves as the God particle is thought to behave—and therefore what its role in the creation and maintenance of the universe is.

"I think we can all be proud ... but it's a beginning," Heuer said.

Higgs Boson Results Exceeded Expectations

The five-sigma results from both the ATLAS and CMS experiments exceeded the expectations of many physicists, including David Evans, leader of the U.K. team that works on the LHC-based ALICE (A Large Ion Collider Experiment) Collaboration.

Evans had predicted Tuesday the teams would announce a four-sigma result—just short of the rigorous standard traditionally required for a new-particle observation to officially count as a true discovery and not a fluke.

"It's even better than I expected," said Evans, of the University of Birmingham in the U.K. "I think we can say the Higgs is here. It exists."

Evans attributed the stronger-than-expected results to "a mixture of the LHC doing a fantastic job" and "ATLAS and CMS doing a fantastic job of improving their analysis since December," when the two teams announced a two-sigma observation of signs of a Higgs-like particle.

"So even with the same data, they can get more significance."

ATLAS spokesperson Fabiola Gianotti also had high praise for the LHC, a multibillion-dollar machine that had suffered numerous mishaps and setbacks in its early days. (Related: "Electrical Glitch Delays Large Hadron Collider."

Here's an excerpt of a blog post from Scientific American:

Our class was recently asked whether or not we felt particle physics research should receive public funding. The majority of us were opposed, our reasons being that such research has no practical value. An instrument as sophisticated and expensive as a particle collider is surely a waste of a nation’s resources.

So it might come as a surprise that plans to build a synchrotron particle collider in Jordan have received overwhelming support from countries in the Middle East, including Iran, Pakistan, the Palestinian Authority and Israel. Scientific discovery is not the only goal being pursued. Those involved hope that this installation, appropriately dubbed SESAME (for Synchrotron-Light for Experimental Science and Applications in the Middle East), will open lines of communication between countries that would not normally work together, and possibly inspire peace.

In John Horgan’s The End of War, he argues that war can be eradicated by simply choosing peace. To support his argument he cites Muzafer Sherif’s famous Robbers Cave Experiment, in which twenty-two fifth-grade boys in a camp were divided into two groups, Rattlers and Eagles, and kept apart for a week, each group growing suspicious of the “others.”

When brought together to compete in games, the groups were alarmingly violent toward one another, having been “manipulated into hating and fighting.” However, once the groups were presented with problems that could only be solved by cooperating with one another, the violence ceased, and they eventually became friends. Sherif saw these interactions as evidence that “traditionally hostile groups can overcome their differences if they are bound together by [a common goal].”

This idea inspired Stanford University physicist Herman Winick more than a decade ago to suggest the synchrotron being dismantled in Germany be sent to the Middle East instead of being scrapped. In the same way that the boys in Sherif’s experiment could only rent a movie if everyone contributed money, a project as expensive as SESAME can only be achieved with funding from multiple countries.

As of 2012, Iran, Israel, Jordan and Turkey have agreed to make contributions of $5 million each to fund the project, which will be based in Jordan and is expected to open in 2015. Pakistan and the Palestinian Authority are willing to give $5 million and $2 million respectively, and Egypt and the United States are both considering making contributions. The project has also been donated spare parts from a number of countries following Germany’s example, and has received funding from the European Union (Science Diplomacy).

Here's an Express Tribune story on Pakistan becoming associate member of CERN:

Pakistan on Friday moved a step closer to becoming associate member of European Organisation for Nuclear Research (CERN), the largest particle physics laboratory in the world.
According to scientists at the National Centre for Physics (NCP) which has been collaborating with CERN since 2000, the CERN Council unanimously approved in principle Pakistan’s name for the process of achieving associate membership, at a meeting on September 17.
The final approval for associate membership depends upon the report of a CERN “fact-finding mission” which will visit Pakistan in February 2014, said Dr Hafeez Hoorani, who is the Director Research at NCP.
The Council’s approval marks the culmination of a process that was initiated by Pakistani scientists in 2008 and has witnessed scientific lobbying, political delays and even a diplomatic campaign by the Pakistani Foreign Office. It also signals the beginning of a process that could potentially lead to Pakistan’s associate membership by the end of 2014.

Located on the Franco-Swiss border near Geneva, Switzerland, CERN conducts some of the most complex scientific experiments of all-time in a bid to understand the structure of the universe. It is the birthplace of the World Wide Web and is home to the world’s largest particle accelerator, the Large Hadron Collider (LHC).
Pakistan is already contributing to CERN projects including designing detection technology and providing personnel support for the LHC’s maintenance. Associate membership could take the level of collaboration up a notch....
---------
The CERN Council consists of 20 member states — all European countries — which are represented by two members each, a scientist and a diplomat. According to NCP scientists, the diplomats were reluctant when Pakistan’s associate membership application came up this year.
CERN has three associate members at present: Serbia, Israel and Ukraine. Responding to a question, Hoorani said Pakistan has also beaten regional neighbour India to the membership process.
Following the approval from the Council, a four-member CERN team led by Director for Research and Computing, Sergio Bertolluci, will visit Pakistan in 2014, he said.

Migration of academics: Economic development does not necessarily lead to brain drain

https://phys.org/news/2023-01-migration-academics-economic-necessarily-brain.html

A team of researchers at the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, developed a database on international migration of academics in order to assess emigration patterns and trends for this key group of innovators. Their paper was published in PNAS on Jan. 18.

As a first step, the team produced a database that contains the number of academics who publish papers regularly, and migration flows and migration rates for all countries that include academics who published papers listed on the bibliographic database Scopus. The migration database was obtained by leveraging metadata of more than 36 million journal articles and reviews published from 1996 to 2021.

"This migration database is a major resource to advance our understanding of the migration of academics," says MPIDR Researcher Ebru Sanliturk. Data Scientist Maciej Danko adds: "While the underlying data are proprietary, our approach generates anonymized aggregate-level datasets that can be shared for noncommercial purposes and that we are making publicly available for scientific research."

MPIDR Researcher Aliakbar Akbaritabar explains how they processed the bibliographic data in order to receive information about the migration patterns of academics: "We used the metadata of the article title, name of the authors and affiliations of almost every article and review published in Scopus since 1996. We followed every single one of the roughly 17 million researchers listed in the bibliographic database through the years and noticed changes in affiliation and, by using that tactic we know how many academics left a given country every year."

The researchers' empirical analysis focused on the relationship between emigration and economic development, indicating that academic setting patterns may differ widely from population-level ones.

Previous literature has shown that, as low-income countries become richer, overall emigration rates initially rise. At a certain point the increase slows down and the trend reverses, with emigration rates declining.

This means that favoring economic development has the counterintuitive effect of initially increasing migration from low- and middle-income countries, rather than decreasing it.

Is this pattern also generally valid for migration of scientists?

Not really.

The researchers found that, when considering academics, the pattern is the opposite: in low- and middle-income countries, emigration rates decrease as the gross domestic product (GDP) per capita increases. Then, starting from around 25,000 US Dollars in GDP, the trend reverses and emigration propensity increases as countries get richer.

MPIDR Director Emilio Zagheni adds, "Academics are a crucial group of innovators whose work has relevant economic effects. We showed that their propensity to emigrate does not immediately increase with economic development—indeed it decreases until a high-income turning point and then increases. This implies that increasing economic development does not necessarily lead to an academic brain drain in low- and middle-income countries."

Unveiling these and related patterns, and addressing big scientific questions with societal implications, was possible only because of painstaking work in preparing this new global database of migration of academics. "We are putting the final touches on an even more comprehensive database, the Scholarly Migration Database, which will be released on its own website soon," says software developer Tom Theile.

Top European Research Labs Select Three teams of Secondary school students-- One Each Netherlands, Pakistan and the US--For Own Accelerator Beam Experiments at CERN and DESY


https://home.cern/news/press-release/cern/three-teams-secondary-school-pupils-netherlands-pakistan-and-usa-win-10th


Geneva and Hamburg, 28 June 2023. In 2023, for the second time in the history of the Beamline for Schools competition, the evaluation committee selected three winning teams. The team “Myriad Magnets” from the Philips Exeter Academy, in Exeter, United States, and the team “Particular Perspective”, which brings together pupils from the Islamabad College for Boys, the Supernova School in Islamabad, the Cadet College in Hasanabdal, the Siddeeq Public School in Rawalpindi and the Cedar College in Karachi, Pakistan, will travel to CERN, Geneva, in September 2023 to perform the experiments that they proposed. The team “Wire Wizards” from the Augustinianum school in Eindhoven, Netherlands, will be hosted at DESY (Deutsches Elektronen-Synchrotron in Hamburg, Germany) to carry out its experiment.


Beamline for Schools (BL4S) is a physics competition open to secondary school pupils from all around the world. The participants are invited to prepare a proposal for a physics experiment that can be undertaken at the beamline of a particle accelerator. A beamline is a facility that provides high-energy fluxes of subatomic particles that can be used to conduct experiments in different fields, including fundamental physics, material science and medicine.

---
“Congratulations to this year’s winners – may they have good beams, collect interesting data and generally have the time of their lives,” says Christoph Rembser, a CERN physicist at the ATLAS experiment and one of the founders of Beamline for Schools. “Every year I am astonished by how many young people submit very creative, interesting proposals. In 2014, we weren’t sure at all whether this competition would work. Ten years and 16 000 participants later, I am proud to say that it is obviously a resounding success.”

The fruitful collaboration between CERN and DESY started in 2019 during the shutdown period of the CERN accelerators. This year, the German laboratory will host its fifth team of winners.

The Pakistan team “Particular Perspective” will measure in detail the beam composition of the T10 beamline of the CERN Proton Synchrotron accelerator. The experiment set-up they designed will make it possible to differentiate between different particle species and measure their intensity.

“I am grateful to BL4S for having provided me with an opportunity to represent my country, Pakistan, and its budding community of aspiring physicists. This is a chance for us to experience physics at the highest level and will inspire people with interests similar to ours to reach greater heights,” says Muhammad Salman Tarar from the “Particular Perspective” team.

The “Wire Wizards” team’s experiment focuses on detector development. The Dutch students designed and built a multi-wire proportional chamber (MWPC), a gas detector able to measure the position of a particle interacting with it, and they plan to characterise it using the electron beam available at DESY.

“The BL4S competition provides us with a unique educational experience that will be a highlight in our time as students,” says Leon Verreijt from the “Wire Wizards” team.

The winners have been selected by a committee of CERN and DESY scientists from a shortlist of 27 particularly promising experiments. All the teams in the shortlist will be awarded special prizes. In addition, one team will be recognised for the most creative video and 10 teams for the quality of physics outreach activities they are organising in their local communities, taking advantage of the knowledge gained by taking part in BL4S.
