Title: Discovery of Higgs particle at Large Hadron Collider and role of Panjab University

Speaker: Prof. J.B. Singh, Department of Physics, Panjab University, Chandigarh

Abstract: On July 4, 2012 discovery of a Higgs-like particle with mass of about 125 GeV/c2 was announced jointly by the CMS and ATLAS collaborations at the European Organization for Nuclear Research (CERN), Geneva. The Higgs particle proposed 50 years was being desperately sought by physicists since the discovery of the massive W and Z bosons at the Super Proton Synchrotron and their detailed study at the LEP accelerators. It was to pursue the discovery of this particle that the world's highest energy accelerator, the Large Hadron Collider (LHC)—commonly called the Big Bang Machine—was built at CERN. With the LHC accelerator protons are accelerated to almost exactly the speed of light. Protons moving with very high speed are made to have head-on collisions in which millions of particles could be produced and among which is the so far elusive Higgs boson particle. Two huge detectors namely the CMS (Compact Muon Solenoid) and ATLAS (A Toroidal Lhc ApparatuS) detectors were designed and built to track the Higgs and possibly other new particles.
Panjab University and Tata Institute of Fundamental Research took complete responsibility of designing, fabrication and testing of one part of the CMS detector. The fabricated detector of Panjab University has been installed and commissioned at CERN and has been partly responsible for the discovery. This seminar would cover the various aspects of contribution of Panjab University. Details of how project was conceived and completed would be presented along with the results of this discovery.
