SQCD Corrections to bg -> bh
Abstract
In the Minimal Supersymmetric Standard Model, the effective b quark Yukawa coupling to the lightest neutral Higgs boson is enhanced. Therefore, the associated production of the lightest Higgs boson with a b quark is an important discovery channel. We consider the SUSY QCD contributions from squarks and gluinos and discuss the decoupling properties of these effects. A comparision of our exact Order(alphas) results with those of a widely used effective Lagrangian approach, the Deltab approximation, is also presented.
