摘要：

The O(alpha-s) QCD corrections to the process t-->W+b are calculated in the standard model for a heavy top quark. For m(W)/M(t) < 0.8, the corrections reduce the partial width by 10% relative to the tree-level result. This reduction of the top-quark width enhances the signal for ttBAR bound-state resonances near threshold in e+e- collisions, studied recently by Strassler and Peskin.
