摘要：

We present an analytic formula for the O(alpha(s)) corrections to the decay t --> H+b for nonzero m(H) and m(b). The equivalence theorem is used to relate these corrections to those for the process t --> W+b. Contrary to previously published results we find that the effect of the b quark mass is negligible for a wide range of m(t), m(H), and tanbeta.
