摘要We introduce an anomalous top quark coupling (right-handed current) into the standard model Lagrangian. Based on this, a more complete calculation of b --> s gamma decay including leading log QCD corrections from mt to M(W) in addition to corrections from M(W) to m(b) is given. The inclusive decay rate is found to be suppressed compared with the case without QCD running from mt to M(W) except at the time of small values of \f(R)(tb)\. For example, when f(R)(tb) = -0.08, it is only 1/10 of the value given before. As \f(R)(tb)\ gets smaller, this contribution is an enhancement as in the standard model case. From the new experiment of the CLEO Collaboration, strict restrictions to parameters of this top-bottom quark coupling are found.
