Description
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 
flavour sector as well as give interesting charged Higgs phenomenology.
