Description
The O(αs) QCD corrections to the process t→W+b are calculated in the standard model for a heavy top quark. For mW/Mt<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 t bar t bound-state resonances near threshold in e+e- collisions, studied recently by Strassler and Peskin
