Description
At the LHC one of the major production channels of neutral Higgs bosons
is gluon fusion. The process is loop-induced where the coupling of the
gluons to the Higgs bosons is mediated by heavy quark and squark loops.
Higher order QCD contributions have turned out to be large. Recently, the
full supersymmetric QCD corrections at next-to-leading order have been
obtained including the full mass dependence of the loop particles. First
results of this calculation will be shown. Also, a conceptual problem,
i.e. the proper treatment of the large gluino
mass limit, will be addressed.
