Description

In this talk I will present the genuine SUSY-QCD corrections to the
production of the pseudoscalar Higgs boson in the Minimal Supersymmetric
Standardmodel (MSSM). These corrections have been numerically calculated
with no expansion in the mass ratios. A comparison to existing
approximations is done in order to see how significant the effects beyond
these approximations are. The (consistent) treatment of $\gamma_5$ is
discussed. The genuine SUSY-QCD corrections can be large in several MSSM
benchmark scenarios and are supplemented by sizeable contributions beyond
the previously known approximations.
