摘要：

We present the two-loop QED and QCD corrections to the f $($) over bar$$ fH Yukawa coupling that are induced by the exchange of a virtual photon or gluon, respectively, with a heavy-fermion loop inserted. As an application, we study the corresponding phi(a(s)(2)M(H)(2)/m(t)(2)) correction to the H --> b $$($) over bar b decay rate.
