Guillelmo Gomez-Ceballos (MIT)06/03/2013 08:30ExperimentOrdinaryThe 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...Aller à la page de la contribution

Dr Fabrice Hubaut (CPPM)06/03/2013 09:00ExperimentOrdinaryLatest 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.Aller à la page de la contribution

Oscar Jose Pinto Eboli (Universidade de São Paulo)06/03/2013 09:30TheoryOrdinaryWe 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...Aller à la page de la contribution

Dr Lidija Zivkovic (LPNHE)06/03/2013 10:35ExperimentOrdinaryThe 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...Aller à la page de la contribution

Mlle Valentina Dutta (MIT)06/03/2013 10:55ExperimentOrdinaryThe 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...Aller à la page de la contribution

Dr Victoria Martin (University of Edinburgh)06/03/2013 11:20ExperimentOrdinaryThe 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,...Aller à la page de la contribution

Heidi Rzehak (CERN)06/03/2013 17:00TheoryOrdinaryIn 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...Aller à la page de la contribution

Wei-Ming Yao (LBL USA)06/03/2013 17:20ExperimentOrdinaryThe 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...Aller à la page de la contribution

M. Joan Elias-Miro (IFAE)06/03/2013 19:10TheoryOrdinaryRecent 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.Aller à la page de la contribution

Dr Mingshui Chen (University of Florida)06/03/2013 19:30ExperimentOrdinaryResults 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.Aller à la page de la contribution
