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.
