The number of collisions, which is the factor used to normalize the pA over pp cross section ratio for hard processes, is calculated within: (i) the Glauber single channel approximation; (ii) adding the Gribov inelastic shadowing corrections; (iii) adding the effects of the short-range NN correlations. The largest effect is found to be related to inclusion or exclusion of the diffractive channels in the trigger.
