Description
Parton distributions in the protons colliding with multiplicity much higher than the mean value, are biased to higher parton densities, leading to enhanced effects of saturation. This and the effect of mutual boosting of the saturation scales significantly increase the gluon density at small x, and correspondingly the production rate of J/psi
and pT broadening, in a good accord with data.
