Higher-order corrections to Higgs-boson decays

Abstract

We review the status of radiative corrections to the decay rates of the Standard-Model Higgs boson in the mass range accessible at LEP~2. Specifically, we consider corrections of ${\cal O}(\alpha)$, ${\cal O}(\alpha_sG_Fm_t^2)$, and ${\cal O}(G_F^2M_H^4)$ to the fermionic decay rates and two-loop QCD corrections to the hadronic decay rates.
