Comments on QCD Corrections to b s γ Decay
Cai-Dian Lü, Jing-Liang Hu, Chong-Shou Gao
Abstract
We find some errors in previous calculation of leading log QCD corrections to b sγ decay, which include corrections from mtop 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=170GeV, the running from mtop to MW results in 13\% enhancement, and for mt=250GeV, 16\% is found.
