Abstract: |
The discovery of a Higgs candidate at the LHC is now official. Before us lies the exciting prospect of experimentally confronting long-standing questions about the nature of electroweak symmetry breaking, and it is possible that the first clear sign of new physics could come from deviations of the Higgs properties from the SM prediction. In work with John Ellis we performed a global analysis of the properties of the ~125 GeV Higgs candidate by combining the latest available data from the CMS, ATLAS and Tevatron experiments, constraining the possible deviations of its couplings from those of a Standard Model Higgs. We show that the couplings of the Higgs candidate are consistent with a linear dependence on particle masses, scaled by the electroweak scale ~ 246 GeV, the power law and the mass scale both having uncertainties ~ 20%. |
