Bruno Lenzi (CERN)27/03/2012, 11:36Electroweak and searchesThe discovery of a neutral Higgs boson with large decay branching fraction to tau and muon pairs, as well as the discovery of a charged Higgs boson would represent a strong evidence of new physics beyond the Standard Model. The experimental results of the searches for the Higgs bosons beyond the Standard Model with the ATLAS detector are reported. The searches are based on an integrated...Go to contribution page

Valentina Santoro (University of Ferrara)27/03/2012, 11:54Electroweak and searchesSeveral types of new-physics models predict the existence of low-mass Higgs states. Previous BABAR searches for leptonic and invisible light-Higgs decays have excluded large regions of model parameter space. We present new searches for hadronic Higgs decays and for a dark-sector Higgs produced in association with a dark gauge boson.Go to contribution page

Emilien Chapon (Centre d'Etudes de Saclay (CEN Saclay)-Unknown-Unknown)27/03/2012, 12:12Electroweak and searchesIn Beyond Standard Model (BSM) theories such as supersymmetry, the electroweak symmetry breaking mechanism predicts one or several Higgs bosons with different couplings and masses compared to the Standard Model one. We will present the constraints on BSM theories coming from searches for exotic Higgs bosons from the CDF and D0 collaborations at the Tevatron. In addition, other bump searches...Go to contribution page

Ennio Salvioni (Universita e INFN (IT))27/03/2012, 14:00Electroweak and searchesWe present the implications of recent LHC results on some classes of Z' and W' models. We also remark how the strongest bounds (coming for example from searches for Z' -> dileptons and W' -> lepton + neutrino) do not apply to some theoretically motivated resonances, and discuss where signals from such states would appear.Go to contribution page

Mr Felix Bruemmer (Heidelberg University)28/03/2012, 08:30Electroweak and searchesThe LHC is closing in on the Minimal Supersymmetric Standard Model. The null results from superparticle searches, and the preliminary evidence for a 124-126 GeV Higgs, severely constrain various popular minimal scenarios. In this talk I will review these constraints, and point out how the LHC results can still be accommodated within the MSSM. The resulting superparticle mass spectra may...Go to contribution page

Carlos Chavez Barajas (CERN)28/03/2012, 10:48Electroweak and searchesSupersymmetry with large mixing between left and right scalar fermions predicts that the lightest partners of the SM fermions belong to the third generation.

Gauginos with masses less than a few hundred GeV can give rise to direct pair production rates at the LHC that can be observed in the data sample recorded in 2011 by the ATLAS...Go to contribution page
