J-PARC Center Ouc. 23, 2012 The 1st J-PARC Colloquium on November 20.   Topic : Origin of Mass in the era of LHC - quest for the Higgs boson -   Guest Speaker : Dr. Guido Tonelli*1, a professor of University of Pisa, Italy and CMS (Compact Muon Solenoid) Spokesperson of LHC (Large Hadron Collider), CERN for the years of 2010-2011   Date : Tuesday, the 20th of November 2012   Time : 3:40 - 5:15 pm (Cookies and coffee will be served from 3:40 pm and the lecture will start at 4:00 pm.)   Location : A conference hall on the 2nd floor of Ibaraki Quantum Beam Research Center(IQBRC)   *1 Short biography Guido Tonelli is a full professor in general physics at the University of Pisa (Italy) and a researcher at the Italian Institute for Nuclear Physics (INFN). He has pursued high-energy physics research in several CERN and Fermilab experiments. The last two decades of his career have been devoted to the search for the Higgs boson and for signatures of new physics beyond the Standard Model. He has been working on the CMS experiment at CERN since 1993, having served as its spokesperson in 2010 and 2011. During his mandate he gives the highest priority to the search for the Standard Model Higgs Boson following personally and directly some of the main activities. On December 13 2011, he presents in a joint CERN Seminar, together with the ATLAS Spokesperson, Fabiola Gianotti, the preliminary results of the analysis of 2011 data containing intriguing hints of the possible presence of the SM Higgs boson in the vicinity of 125GeV/c2. After the formal announcement of the discovery of the Higgs boson by ATLAS and CMS on July 4th 2012, those hints are now considered the first evidence of the presence of the new particle in LHC data. He is author of more than 500 scientific publications with average index of citations exceeding 50.   Webmaster:<web-staff@j-parc.jp>
