“…In all these approaches, if there are no limitations, fluctuations increasingly dominate over average multiplicity: D 2 / n 2 increases and, asymptotically, it may reach a constant value (KNO scaling [3]). This kind of behaviour, as pointed out in [4], has been observed long ago in cosmic ray physics [5], with the negative binomial parameter k stabilising at a value of the order of 2.5-3, for √ s ≥ 1 TeV.…”

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 √ s 1800 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.

This paper contains a review of the main results of a search of regularities in collective variables properties in multiparticle dynamics, regularities which can be considered as manifestations of the original simplicity suggested by QCD. The method is based on a continuous dialog between experiment and theory. The paper follows the development of this research line, from its beginnings in the seventies to the current state of the art, discussing how it produced both sound interpretations of the most relevant experimental facts and intriguing perspectives for new physics signals in the TeV energy domain.

“…Indeed, the Pascal regularity [1] appeared very soon: that final charged particle MD's were well described by the negative binomial (NB), also known as Pascal, distribution was discovered first in cosmic rays observations [2] in the '60, and later confirmed in the 5-100 GeV energy range in pp collisions and up to 40 GeV in e + e − annihilations, as well as in other types of collisions (see, e.g., [3]. ) The NB (Pascal) distribution is a two-parameter distribution:…”
