摘要：We average the decay width of a heavy meson in the t' Hooft model over the heavy quark mass M with a smooth weight function. The averaging has support over a few resonance spacings. We use the previously determined heavy meson decay width which di ers from the free quark width by a 1=M correction. In contrast, we nd that the averaged meson and quark widths di er by a 1=M2 correction. We speculate on the relevance of our results to the phenomenologically relevant case of 3+1 dimensional QCD
