Title: Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC Authors: The ATLAS Collaboration Categories: hep-ex Comments: 24 pages plus author list (39 pages total), 12 figures, 7 tables, submitted to Physics Letters B Report-no: CERN-PH-EP-2012-218 \\ A search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC is presented. The datasets used correspond to integrated luminosities of approximately 4.8 fb^-1 collected at sqrt(s) = 7 TeV in 2011 and 5.8 fb^-1 at sqrt(s) = 8 TeV in 2012. Individual searches in the channels H->ZZ^(*)->llll, H->gamma gamma and H->WW->e nu mu nu in the 8 TeV data are combined with previously published results of searches for H->ZZ^(*), WW^(*), bbbar and tau^+tau^- in the 7 TeV data and results from improved analyses of the H->ZZ^(*)->llll and H->gamma gamma channels in the 7 TeV data. Clear evidence for the production of a neutral boson with a measured mass of 126.0 +/- 0.4(stat) +/- 0.4(sys) GeV is presented. This observation, which has a significance of 5.9 standard deviations, corresponding to a background fluctuation probability of 1.7x10^-9, is compatible with the production and decay of the Standard Model Higgs boson. \\ ( http://arxiv.org/abs/1207.7214 , 334kb) ------------------------------------------------------------------------------ \\ arXiv:1207.7235 Date: Tue, 31 Jul 2012 13:27:18 GMT (2076kb,D) Title: Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC Authors: The CMS Collaboration Categories: hep-ex Comments: Submitted to Phys. Lett. B Report-no: CMS-HIG-12-028; CERN-PH-EP-2012-220 \\ Results are presented from searches for the standard model Higgs boson in proton-proton collisions at sqrt(s)=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: gamma gamma, ZZ, WW, tau tau, and b b-bar. An excess of events is observed above the expected background, a local significance of 5.0 standard deviations, at a mass near 125 GeV, signalling the production of a new particle. The expected significance for a standard model Higgs boson of that mass is 5.8 standard deviations. The excess is most significant in the two decay modes with the best mass resolution, gamma gamma and ZZ; a fit to these signals gives a mass of 125.3 +/- 0.4 (stat.) +/- 0.5 (syst.) GeV. The decay to two photons indicates that the new particle is a boson with spin different from one. \\ ( http://arxiv.org/abs/1207.7235 , 2076kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ Beberapa sumber informasi tambahan Seminar di CERN, 4 Juli http://cdsweb.cern.ch/record/1459565 Slide presentasi di CERN, 4 Juli http://indico.cern.ch/conferenceDisplay.py?confId=197461 Seminar di International Conference on High Energy Physics (ICHEP), 9 Juli https://cdsweb.cern.ch/record/1460446 Slide presentasi di ICHEP, 9 Juli https://indico.cern.ch/sessionDisplay.py?sessionId=16&confId=181298#20120709 CERN YouTube, yang memuat beberapa video seminar maupun penjelasan semi populer http://www.youtube.com/user/CERNTV ------------------------------------ =============================================================== ** Arsip : http://members.tripod.com/~fisika/ ** Ingin Berhenti : silahkan mengirim email kosong ke : <fisika_indonesia-unsubscr...@yahoogroups.com> =============================================================== Yahoo!
