Guillelmo Gomez-Ceballos (MIT)3/6/13, 8:30 AMExperimentOrdinaryThe status of the Standard Model Higgs Boson search in the bosonic decay channels at the CMS experiment at the LHC will be presented. The results will be based on proton-proton collisions data corresponding to integrated luminosities of up to 5.1 fb-1 at sqrt(s) = 7 Tev and 19.6 fb-1 at sqrt(s) = 8 TeV. The observation of a new boson at a mass near 125 GeV should be confirmed by the analysis...Go to contribution page

Dr Fabrice Hubaut (CPPM)3/6/13, 9:00 AMExperimentOrdinaryLatest studies of Standard Model Higgs to diboson states with the ATLAS experiment are reported. Emphasis will be given to the property measurements (mass, couplings, spin-parity) performed in the different channels.Go to contribution page

Oscar Jose Pinto Eboli (Universidade de São Paulo)3/6/13, 9:30 AMTheoryOrdinaryWe study the indirect effects of new physics on the phenomenology of the recently discovered state associated to the electroweak symmetry breaking sector. In a model independent framework these effects can be parametrized in terms of an effective Lagrangian at the electroweak scale. In a theory in which the SU(2)_L x U(1)_Y gauge symmetry is linearly realized they appear at lowest order as...Go to contribution page

Dr Lidija Zivkovic (LPNHE)3/6/13, 10:35 AMExperimentOrdinaryThe CDF and D0 experiments at the Tevatron $p\bar{p}$ Collider were collecting data between 2002 and 2011. During that time, the extensive search for the standard model Higgs boson was performed. Every accessible decay mode was investigated. Results from the searches for the standard model Higgs boson with the final dataset will be presented for individual channels, as well as combined...Go to contribution page

Ms Valentina Dutta (MIT)3/6/13, 10:55 AMExperimentOrdinaryThe latest results of the search for the SM scalar boson in fermionic decay channels at the CMS experiment are presented. The dataset used corresponds to an integrated luminosity of 5 fb-1 of pp collision data collected at sqrt(s) = 7 TeV and up to 19.4 fb-1 collected at sqrt(s) = 8 TeV. The analyses described include the searches for the SM scalar boson decaying to tau pairs and to a pair of...Go to contribution page

Dr Victoria Martin (University of Edinburgh)3/6/13, 11:20 AMExperimentOrdinaryThe discovery of a Higgs-like boson by the ATLAS collaboration relies on evidence from di-boson decays: γγ, ZZ∗ and WW∗. The Standard Model predicts that the Higgs boson with mH∼125GeV should also have significant branching ratios to pairs of bottom and charm quarks and tau-leptons and muons. Decays to these final states are significantly more challenging to detect due to large backgrounds,...Go to contribution page

Heidi Rzehak (CERN)3/6/13, 5:00 PMTheoryOrdinaryIn the light of the discovery of a Higgs boson like particle and no evidence of particles beyond the Standard Model the question arises: How much can the coupling of the Higgs boson to other particles deviate from the Standard Model Higgs couplings if no further particles will be discovered at the LHC and how precise have Higgs coupling measurements to be to capture these deviations? In the...Go to contribution page

Wei-Ming Yao (LBL USA)3/6/13, 5:20 PMExperimentOrdinaryThe Tevatron combination of searches for BEH boson and studies of its properties will be presented. The searches use up to 10 fb-1 of Tevatron collider Run II data. We observe a significant excess of events in the mass range between 115 and 140 GeV/c2. The local significance corresponds to 3.1 Gaussian standard deviations at the mass of 125 GeV/c2. Furthermore, we separately...Go to contribution page

Mr Joan Elias-Miro (IFAE)3/6/13, 7:10 PMTheoryOrdinaryRecent studies have shown that, for the current experimental values of M_H, M_t and \alpha_s, the SM scalar potential develops a second minimum, deeper than the electroweak (EW) one. I will review a simple and efficient mechanism to stabilize the EW vacuum. The mechanism involves an extra scalar singlet and can be operative in existing see-saw, invisible axion and unitarized Higgs inflation models.Go to contribution page

Dr Mingshui Chen (University of Florida)3/6/13, 7:30 PMExperimentOrdinaryResults are presented on the measurement of the properties of the new state that was discovered in the search for a Higgs boson. These include combined measurements of the mass of the new state as well as its tensor structure (spin, CP) and coupling to other particles, using the 7 and 8 TeV datasets of pp collisions.Go to contribution page
