摘要The rare decay H --> gamma gamma is a promising detection channel for an intermediate mass Higgs boson. We compute its two-loop O(alpha(2)G(F)m(t)(2)) correction in the standard model and find that the relative correction to the decay rate runs between 0.7% and 0.5% for M(H) = 80-150 GeV, which is of the same order as the corresponding QCD correction. The analogous correction to the amplitude for gg --> H is recovered as a special case. The generalization of our result to other models is also briefly indicated. (C) 1997 Elsevier Science B.V.
