What’s next after the Higgs boson discovery: toward Beyond the Standard Model
Hwidong Yoo, Seoul National University
The Large Hadron Collider (LHC) is the most powerful particle collider in the history and the Compact Muon Solenoid (CMS) Experiment is one of two large general-purpose detectors built on the LHC. They have started the first data taking since 2010 and finally the Higgs bo son has been discovered in 2012, which is the last piece of the Standard Model (SM), sometimes referred to as the “God Particle”. Prof. F. Englert and P. Higgs were jointly awarded the 2013 Nobel Prize for the contrib ution to our understanding of the origin of mass of subatomic particles by the Higgs mechanism. Nevertheless the SM does not fully account for many issues facing current particle physics fields such as the hierarchy problem, CP violation, neutrino mass, dark matter and dark energy. Unifi cation with gravity is also not cont ained in the SM. It is clear, therefore, that there must be a rich field of physics beyond the SM (BSM). New particles or phenomena predicted from the BSM are expected to observe in near future at the LHC. Brief overview for highlights of direct and indirect BSM searches at the LHC we particle physicists do recently is presented.
