摘要
We consider the decay of an intermediate mass Higgs boson into hadrons up to order O(alpha(s)(3)). The results from the diagrams containing only light degrees of freedom were recently computed in a previous work by K.G. Ch. [Phys. Lett. B 390 (1997) 309]. In this letter the remaining contributions involving the top quark are evaluated analytically using an effective field theory approach. Coupled with the previous result the present calculation determines the complete next-next-to-leading order correction to the hadronic decay rate of an intermediate mass Higgs boson.
