摘要: The electroweak $\mathcal O(\alpha)$ radiative corrections to the decay of heavy CP-even MSSM Higgs boson weak gauge bosons are presented. Due suppression tree-level $H^0WW/H^0ZZ$ coupling, contributions partial width significant. Although effective Born can be rather small for certain $M_{A^0}$ values (especially large $\tan\beta$), corrected widths at different comparable size.
