Is the scalar Higgs boson observed at the LHC, a supersymmetric Higgs boson or a standard model one?

Abstract

Recently, a SM-like Higgs particle is reported to be discovered at CMS and ATLAS experiments at CERN with a mass of about 124 GeV. The present paper is related to an attempt to understand a very important question: Is the scalar Higgs boson observed at the LHC, a supersymmetric Higgs boson or a standard model one? Actually, after briefly reviewing the theoretical studies on Higgs mass in the context of Standard Model (SM) and Minimal Supersymmetric Standard Model (MSSM), we compare the values of Higgs mass obtained in several theoretical works on SM and MSSM, including those of the present author. We comment critically as regards the identification of the Higgs boson as SM Higgs or MSSM Higgs. In particular, certain models show that MSSM can give the mass of the lightest Higgs at a value near the observed value of nearly 124 GeV of SM-like Higgs, for a suitable choice of parameters. We suggest that repeated experimental confirmation as well as studies of other distinguishing properties of the discovered Higgs particle can probably discriminate the SM Higgs boson from the lightest MSSM one?
