摘要：

QCD corrections to the electroweak one-loop result for the partial width GAMMA(H --> bbBAR) are studied. For the decay channel into bottom quarks the rate is affected by a virtual top quark through electroweak interactions. The calculation of QCD corrections to this quantity is performed for an intermediate range Higgs mass in the heavy top mass limit. The leading correction of order O(G(F)alpyha(s)m(t)2) is estimated. Numerically the contribution is of the same size as the electroweak correction.
