Radiative corrections to $h^0\to W{W}^{\ast }/Z{Z}^{\ast }\to 4$\,leptons in the MSSM

Abstract

The electroweak $\text{mc}O(\alpha )$ radiative corrections to the decay of the lightest MSSM Higgs boson to four leptons are presented, improved by the two-loop corrections provided by the program package FeynHiggs. We also analyze the results in the decoupling limit and investigate the numeric impact of contributions from the genuine supersymmetric particle spectrum.
