Abstract

We analyze neutral Higgs boson decays into squark pairs in the minimal supersymmetric extension of the standard model and improve previous analyses. In particular the treatment of potentially large higher-order corrections originating from the soft supersymmetry-breaking parameters A_b, the trilinear Higgs coupling to sbottoms, and \ensuremathμ, the Higgsino mass parameter, is investigated. The remaining theoretical uncertainties including the supersymmetric QCD corrections are analyzed quantitatively.
