Abstract

The renormalization of the amplitudes of the second order in weak interactions by strong interactions in calculated. The strong interactions are assumed to be connected with the colour SU(3)′ group while weak interactions are described by the Weinberg-Salam model. It is shown, in particular, that the bounds on the masses of charmed particles are affected only weakly by the account of strong interactions.
