Abstract

We calculate the ratio of the two branching ratios, Br(h→bb̄) and Br(h→cc̄)+Br(h→gg), in the minimal supersymmetric standard model taking into account the SUSY-loop corrections to the Higgs sector and the hbb̄ vertex. We show that the heavy Higgs mass can be extracted from the ratio, almost independently of other SUSY parameters, in the region of tan β≲10.
