摘要：

Two-photon decay of the Higgs boson H --> gammagamma and its reverse process gammagamma --> H are important processes in detecting Higgs boson which plays a fundamental role in the Standard Model of electroweak interaction. We calculate the QCD corrections to these processes for all mass ranges of the Higgs boson without any constraint for the top quark mass. For a heavy Higgs boson (m(H) >> m(t)), the QCD corrections become very large (50-100%), while for a lighter one (m(H) less-than-or-equal-to m(t)), the corrections are negligible.
