Higgs Sector of NMSSM in the Light of Higgs Discovery

In the framework of non minimal supersymmetric model, assuming one of the CP even Higgs as the discovered SM like Higgs bosons, we revisit the phenomenology of Higgs sector. Due to the presence of singlet-doublet mixing, the couplings of Higgs bosons can be reduced and lead to very light Higgs bosons that are allowed by LEP, Tevatron and even the LHC 8 TeV runs. We present the mass spectrum of non SM like Higgs bosons and couplings with fermions and gauge bosons checking the consistency with all experimental data. We also studied the branching ratios (BR) of these non SM like Higgs bosons in various channel. It is found that the BR of non-SM Higgs boson in the two photon channel is very large (even up to 90 %) and provides a rich phenomenology in LHC.
