Abstract

We calculate the radiative corrections to the nonleptonic inclusive B decay mode b → cud taking into account the charm quark mass. Compared to the massless case, corrections resulting from a nonvanishing c quark mass increase the nonleptonic rate by (4-8)%, depending on the renormalization point. As a by-product of our calculation, we obtain an analytic expression for the radiative correction to the semileptonic decay b → uτv taking into account the τ lepton mass, and estimate the c quark mass effects on the nonleptonic decay mode b → ccs. © 1994.
