Description
It is experimentally observed that the width of the KNO multiplicity distribution-or the negative binomial parameter, 1/k-for pp collisions, in the energy region 10-bar s-bar 1800-bar GeV, is an increasing function of the energy. We argue that in models with parton or string saturation such trend will necessary change: at some energy the distribution will start to become narrower. In the framework of percolating strings, we have estimated the change to occur at an energy of the order of 5-10 TeV
