J-PARC Center November 28, 2012 Held 1st J-PARC Colloquium on November 20 The Origin of Mass in the Era of LHC: Quest for the Higgs Boson   The 1st J-PARC Colloquium was held at the Ibaraki Quantum Beam Research Center on November 20, 2012. The lecture concerned experiments looking for new particles such as the Higgs boson, which is thought to impart mass to all particles, at the European Organization for Nuclear Research (CERN). The invited speaker was Dr. Guido Tonelli (Professor, University of Pisa, Italy), previously the leader of CERN's CMS (Compact Muon Solenoid) Experiment team, which includes many researchers from Europe and the US. He gave an extremely interesting talk on the background of the discovery of the Higgs boson, the only elementary particle predicted by the Standard Model of particle physics which had yet to be found; new scientific progress due to the discovery of the Higgs boson, such as elucidation of the origin of mass and the mystery of the creation of the universe; and expectations for new physics going beyond the Standard Model.   The CMS Experiment is a high-energy frontier experiment being carried out by two international research groups at the Large Hadron Collider (LCH) straddling the border between Switzerland and France. On July 4, 2012, CERN announced that the existence of a particle believed to be the Higgs boson was observed in these two experiments, CMS and ATLAS (A Troidal LHC Apparatus).     * To see the video clips, you need a plug-in.
