摘要：

It is shown that up to an overall scale the lowest-older QCD corrections to t --> H+b and to t --> W+b are the same in the heavy-top-quark limit. Asymptotically, they are given by - (4alpha(s)/3pi) [pi2/3 - 5/4], resulting in a reduction in the decay rate by about 9%, rather than 6% reported previously in the literature. This is verified explicitly by an analytic calculation. The application of the equivalence theorem to this process is also discussed.
