ISLAMABAD - Francois Englert from Belgium and Peter Higgs from UK have been jointly awarded the Nobel Prize in Physics 2013 for the discovery of "Higgs Boson", the so called "God particle".
The prize winning theory is central part of the Standard Model of particle physics that discusses how fundamental forces can be combined into a single unified force, a theory pioneered by Prof. Abdus Salam. The theory proposed by Englert and Higgs, in 1964, describes how elementary particles acquire mass. According to a press release of Pakistan Atomic Energy Commission Pakistani scientists have long been collaborating informally with CERN with Prof. Slam providing strong link to CERN.
Pak-CERN cooperation was formally started in 1994 with the signing of a mutual cooperation agreement between Government of Pakistan and CERN signed by the then Chairman, PAEC and the then DG, CERN. The PAEC played a leading role in establishing ties with CERN and took responsibility of constructing 8 out of 10 Magnet Supports for CMS detector.
Magnet Supports are installed at CERN today with the label 'Made in Pakistan'.
Similarly, later in the year 2000, Pakistan took another major initiative when PAEC along with National Center for Physics (NCP) made commitment to supply Resistive Plate Chamber (RPC). The PAEC was also involved in the central tracker laser alignment system for the CMS experiment.
The PAEC scientists and engineers have also contributed in the construction of ATLAS experiment. The important role played by PAEC regarding the timely supply and excellent quality of vital parts of the detectors was recognized by CERN through granting 'Best Supplier Award' in 2006. Pakistani scientists are also involved in the analysis of the enormous data being generated by LHC experiments. High performance computational grids have been established at NCP and COMSATS where huge data is constantly being received from CMS and ALICE through large bandwidth data link with CERN.
One of the early signals indicating the presence of the Higgs Boson came from RPCs made in Pakistan. In September 2012, CERN management, in a complimentary letter to Chairman PAEC, recognized the services of Pakistan and presented a CMS cooperation shield.
The existence of Higgs Boson was verified during LHC experiments at CERN in 2012.
Pakistan can proudly claim that in these experiments, not only during the initial period of infrastructure erection but also during experimental phase, Pakistani scientists and engineers significantly contributed in this international venture.
As recognition of the efforts made by Pakistani scientists and engineers in the past and the ongoing various collaborations programs with CERN,
Pakistan has been accepted as a candidate to become an associate member of CERN.
A technical team from CERN is going to visit Pakistan in the near future to assess scientific and technical base. Pakistan will be the first country in South Asia to acquire the status of associate member of CERN.

Large Hadron Collider: In high-end research, Pakistanis also playing their part – The Express Tribune

ISLAMABAD: Many Pakistanis may not be aware that their country’s contributions to some of the most important scientific experiments and discoveries in the world did not end with the late Dr Abdus Salam, the only Pakistani ever to win the Nobel Prize in Physics.

In fact, at the European Organisation for Nuclear Research (CERN), not only did electronics manufactured in Pakistan help in the detection of the Higgs boson, the elementary particle scientists believe imparts mass to all particles, Pakistani engineers and technicians are also currently participating in repairs of the Large Hadron Collider (LHC), the highest energy particle accelerator in the world.

Pakistan’s collaboration with CERN, the world’s largest particle physics laboratory, first started in 1994 through the efforts of the Pakistan Atomic Energy Commission (PAEC), said Dr Hafeez Hoorani, the director of research at the National Centre for Physics (NCP) in Islamabad. The NCP became a part of PAEC’s collaboration with CERN after it was established in 1999.

At present, the NCP is one of the hundreds of grid nodes in the world that receive scientific data from the LHC, which are being used by NCP researchers and students.

“We as a nation should be proud of the fact that today Pakistan is part of an experiment which is the most exciting and challenging experiments of all times,” Hoorani, who has worked at CERN himself, said. “This project helps our students get involved in cutting-edge research.”

The LHC collides two high-energy, unbelievably fast beams of elementary particles, so scientists can test scientific models on the interaction of subatomic particles.

The Higgs boson — until the announcement of its discovery on July 4, 2012, the Higgs was the only missing element in the Standard Model of Physics, a model that Salam contributed to through his work on electroweak theory — decays instantaneously, so scientists had to confirm its existence through particles formed by its decomposition.

One of those by-product particles, a “Muon,” is detected by the CMS and Pakistan has been a full member of the CMS experiment since 2000.

Hoorani said around half of the events detected by the CMS, which were consistent with the hypothesis of the Higgs boson, were observed using detectors made in Pakistan.

The construction of these detectors, called Resistive Plate Chambers (RPCs), was made possible by the work of 15 physicists, 10 engineers, five Lasers and Opto-electronics experts, six computer professionals and 20 students from NCP and PAEC, Hoorani said.


The process included assembling and testing of 288 RPCs, the fabrication of mechanical pieces for LHC and the design of tracker alignment for the CMS. The PAEC also assembled carbon frames for the detector’s outer barrel at a cost which is approximately one-third of the European cost. In 2006, CERN awarded PAEC its Best Suppliers Award.

If that is not enough, two teams of Pakistani experts are participating alongside teams from Greece, Bulgaria, Poland and Italy in the LHC’s maintenance process that will continue till the end of 2014.

Twenty-eight people were selected from Pakistan after interviewing candidates from NCP, PAEC, the Heavy Mechanical Complex in Taxila and Precision Engineering in Karachi, Hoorani said. The engineers and technicians were trained at a mock-up facility at PAEC to familiarise them with the LHC environment and tools.


One six-member welding team and a six-member mechanical team have been working in Geneva, Switzerland, where CERN is located, since April on a nine-month shift.
NCP Director General Hamid Saleem said Pakistan is also trying to extend its collaboration with CERN in the coming months.
