New Particle at the Large Hadron Collider

Abstract

On July 4, 2012 two experiments, working at the CERN Large Hadron Collider, jointly announced a strong evidence of observing a new particle state. The observed particle, approximately 135 times heavier than proton and with a very short life time, could be the elusive Higgs boson which the high energy physicists have been earnestly looking for during the past 25 years. This will close one of the puzzles of the Standard Model of particle physics. More recent data have demonstrated some of the intrinsic properties of this new particle. The search involved a consolidated effort from thousands of physicists from all over the world over two decades. The challenges in this search and Indian effort in this process will be discussed.
