Descripción
We will discuss the recent Higgs discovery results both by CMS and ATLAS at the LHC. In this context we will consider the status of supersymmetric scenarios. In minimal supersymmetric scenarios in order to have a $\sim 125$ GeV Higgs, one needs large quantum corrections from strong supersymmetric sectors and either large supersymmetric mass scale or large mass splitting between the contributing super-particles is demanded.
We focus on the triplet extension of minimal supersymmetric scenario, where we can see that the electroweak contributions coming from triplet are also important and comparable to the strong contributions. We discuss this in the context of the observed Higgs like particle around 125 GeV and also look into the status of other Higgs bosons in the model. We also calculate in this model the Br($B_s \to X_s \gamma$) which has contributions coming from
three physical charged Higgs bosons and three charginos. In articular the doublet-triplet mixing plays an important role in constraining the parameter space. In this context we also discuss the phenomenology of light charged Higgs probing $H^\pm_1-W^\mp-Z$ coupling at the LHC.
