| Abstract: | We find some errors in the previous calculation of leading log QCD corrections to b + sγ decay, which include corrections from mto, to Mw in addition to corrections from Mw to mb. The inclusive decay rate is found to be enhanced more than previous calculations. At mt = 170 GeV, the running from mtop to Mw results in 13% enhancement, and for mt = 250 GeV, 16% enhancement is found. |
