Supersymmetric QCD corrections to associated Higgs boson-bottom quark production

The associated production of a Higgs boson with a b quark is a discovery mode for a minimal supersymmetric standard model (MSSM) Higgs boson at large tan beta. We compute the SUSY QCD corrections from gluino and squark loops to this process and combine them with the O(alpha(2)(s)) next-to-leading order (NLO) QCD corrections to obtain reliable predictions for the rate. Finally, we compare our results with an effective Lagrangian approximation which includes only the low energy corrections from squark and gluino loops to the b (b) over bar Higgs vertices.
