QCD radiative enhancement of the decay b -> c cbar s

Abstract

A substantial enhancement is found of the $b\to c\overline{c}s$ decay rate due to the QCD interaction within the $\overline{c}s$ pair, which enhancement may amount to 30\%, or more. Some general features of calculation of the QCD radiative corrections in two first orders are discussed.
