| 英文摘要 | We give a more complete calculation of b --> s gamma decay, including leading log QCD corrections from m(t) to M(W) in addition to corrections from M(W) to m(b). We have included the full set of dimension-6 operators and corrected numerical mistakes of anomalous dimensions in a previous paper [14]. Compared with the calculations without QCD running from m(t) to M(W), the inclusive decay rate is found to be enhanced. At m(t) = 150 GeV, it results in a 12% enhancement, and for m(t) = 250 GeV, 15% is found. The total QCD effect makes an enhanced factor of 4.2 at m(t) = 150 GeV, and 3.2 for m(t) = 250 GeV. |
