Abstract
We investigate the decoupling properties of the Higgssectorinduced oneloop corrections in the lightest Higgsboson selfcouplings, in the framework of the minimal supersymmetric standard model (MSSM). The renormalized npoint vertex functions with external Higgs particles in the MSSM and in the SM are derived to the oneloop level and compared in the M(A)(0)much greater thanM(Z) limit. The computation has been done in a general Rxi gauge and the onshell renormalization scheme is chosen. By a comparison of the renormalized lightest Higgsboson h(0) vertex functions with respect to the corresponding SM ones, we find that the differences between the predictions of both models are summarized in the lightest Higgsboson mass correction DeltaM(h)(0). Consequently, the radiative corrections are absorbed in the Higgsboson mass, and the trilinear and quartic h(0) selfcouplings acquire the same structure as the couplings of the SM Higgs boson. Therefore, decoupling of the heavy MSSM Higgs bosons occurs and the MSSM h(0) selfinteractions converge to the SM ones in the M(A)(0)much greater thanM(Z) limit.
