We compute the complete next-to-leading order SUSY-QCD corrections for the associated production of a charged Higgs boson with a top quark via bottom-gluon fusion. We investigate the applicability of the bottom parton description in detail. The higher order corrections can be split into real and virtual corrections for a general two Higgs doublet model and into additional massive supersymmetric loop contributions. We find that the perturbative behavior is well under control. The supersymmetric contributions consist of the universal bottom Yukawa coupling corrections and nonfactorizable diagrams. Over most of the relevant supersymmetric parameter space the Yukawa coupling corrections are sizable, while the remaining supersymmetric loop contributions are negligible.

Bottom-quark associated Higgs-boson production: reconciling the four- and five-flavour scheme approach (2011, background): “The large factorization scale μF ≈ mH/4 corresponds to the upper limit of the collinear region up to which factorization is valid [1, 2, 3].”
