摘要：

The Higgs decay into two photons H --> gamma-gamma plays a crucial role for searching this particle in the intermediate mass range at the future pp colliders LHC and SSC. Photon-photon fusion, on the other hand, provides a most important source for Higgs particles in high-energy e+e- colliders. Besides the W loop, the H-gamma-gamma coupling is built up by heavy quark loops. We present the result of the (two-loop) radiative QCD correction to this process for a Higgs particle in the intermediate mass range. Being of order alpha-s/pi, this correction is well under control.
