摘要：

In recent papers QCD corrections to the decay t --> H+b were calculated by two groups with results that disagreed. Using dimensional regularization for both infrared and ultraviolet divergences, we confirm that the QCD corrections to the decay width GAMMA(t -> H+b) are equal to GAMMA(t --> W+b) in the limit of a large t-quark mass.
