Properties of 125 GeV Higgs boson in non-decoupling MSSM scenarios

Abstract

Tantalizing hints of the Higgs boson of mass around 125 GeV have been reported at the LHC. We explore the MSSM parameter space in which the 125 GeV state is identified as the heavier of the CP even Higgs bosons, and study two scenarios where the two photon production rate can be significantly larger than the standard model (SM). In one scenario, $\Gamma (H\to \gamma \gamma )$ is enhanced by a light stau contribution, while the $W{W}^{\ast }$ ($Z{Z}^{\ast }$) rate stays around the SM rate. In the other scenario, $\Gamma (H\to b\bar{b})$ is suppressed and not only the $\gamma \gamma$ but also the $W{W}^{\ast }$ ($Z{Z}^{\ast }$) rates should be enhanced. The $\tau \bar{\tau }$ rate can be significantly larger or smaller than the SM rate in both scenarios. Other common features of the scenarios include top quark decays into charged Higgs boson, single and pair production of all Higgs bosons in $e^{+}{e}^{-}$ collisions at $\sqrt{s}\lesssim 300$ GeV.
