## Abstract

We investigate the decoupling properties of the Higgs-sector-induced one-loop corrections in the lightest Higgs-boson self-couplings, in the framework of the minimal supersymmetric standard model (MSSM). The renormalized n-point vertex functions with external Higgs particles in the MSSM and in the SM are derived to the one-loop level and compared in the M(A)(0)much greater thanM(Z) limit. The computation has been done in a general R-xi gauge and the on-shell renormalization scheme is chosen. By a comparison of the renormalized lightest Higgs-boson 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 Higgs-boson mass correction DeltaM(h)(0). Consequently, the radiative corrections are absorbed in the Higgs-boson mass, and the trilinear and quartic h(0) self-couplings 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) self-interactions converge to the SM ones in the M(A)(0)much greater thanM(Z) limit.
