Analytical Result for the Two-Loop QCD Correction to the Decay H --> 2 gamma

arXiv:hep-ph/0401090 · doi:10.1016/j.physletb.2004.01.063

Abstract

An analytic formula for the two-loop QCD correction of the decay H --> 2 gamma is presented. To evaluate all master integrals a `Risch-like' algorithm was exploited.
