The interpretation of the Higgs signal within the MSSM requires precise theoretical predictions including mixing and higher-order effects.

Recent data on 125 GeV Higgs-like boson at the LHC starts to constrain the electroweak symmetry breaking sector of the SM and its various extensions. If one imposes the local gauge symmetry of the Standard Model (SM) (SU(3)c×SU(2)L×U(1)Y) to the SM and any possible new physics scenarios, the SM Higgs properties will be modified by intrinsically two different ways: by new physics either...
