Abstract

The most likely scenario in the light of Higgs discovery is the decoupling limit in the MSSM Higgs sector. The decoupling limit in MSSM occurs when the pseudoscalar mass is large (i.e.mA» mZ ), then the CP-even (H0), CP-odd (A0) and charged (H±) Higgs are mass degenerate and the lightest CP-even Higgs boson (h) mimics the signature of the SM Higgs boson. In the decoupling limit of large mA the couplings of the lightest CP-even MSSM Higgs boson h to pairs of SM particles approach their SM values. Moreover, in the decoupling limit there exists a value of tanβ which is independent of the value of mA . Recently a Higgs like particle is reported to be discovered at CMS and ATLAS experiments at CERN LHC with a mass of about 125 GeV. This estimate is only valid in the so called decoupling limit where all non-standard Higgs bosons are significantly heavier than the Z gauge boson.
