Higgs bosons: discovered and hidden, in extended supersymmetric standard models at the LHC

We will discuss the recent Higgs discovery results both by CMS and ATLAS at the LHC.
In this context we will see the status of supersymmetric scenarios. In minimal supersymmetric scenarios to have a $\sim 125$ GeV Higgs, one needs quantum correction
from strong supersymmetric sector which demands either large suspersymmetric mass scale or large mass splitting between the contributing super-particles.

We focus on the triplet and singlet extensions of
minimal supersymmetric scenario, where we can see
that the electro-weak contributions coming from the additional triplet and singlet are also important and comparable to the strong contributions. In the context of the observed Higgs like particle around 125 GeV, we look into the status of other Higgs bosons in the model. The possibility of axion like pseudo-scalar gives rise to interesting phenomenology.
Doublet-triplet and doublet-singlet mixings in the Higgs sector have implications in the flavor sector as well as give interesting charged Higgs phenomenology.
