5 AS-ITP 957 b → sγ Decay and Right-handed Top-bottom Charged Current


We introduce an anomalous top quark coupling (right-handed current) into Standard Model Lagrangian. Based on this, a more complete calculation of b → sγ decay including leading log QCD corrections from m top to M W in addition to corrections from M W to m b is given. The inclusive decay rate is found to be suppressed comparing with the case without QCD… (More)
