Abstract
We continue to investigate the effects of the (dominant) subleading operator of the σH type in the 1/ N c parts of the weak nonleptonic amplitudes. If the previous work concentrated on exclusive decays now we analyse inclusive widths in a certain kinematic limit. Deviations from the parton model predictions are found due to soft-gluon color exchange. In the interference (i.e. 1/ N c) terms they are stronger than in the non-interferene terms. The sign is negative so that the 1/ N c parts tend to cancel. The absolute value of the effect is of order 1 in D-mesons and of order 0.25 in B-mesons.
