The net-baryon production at forward rapidities is investigated considering the Color Glass Condensate formalism. We assume that at large energies the coherence of the projectile quarks is lost and that the leading baryon production mechanism changes from recombination to independent fragmentation. The phenomenological implications for net-baryon production in pp/pA/AA collisions are analysed and predictions for LHC energies are presented.

Multiplicity distributions P (N ) measured in multiparticle production processes are most frequently described by the Negative Binomial Distribution (NBD). However, with increasing collision energy some systematic discrepancies have become more and more apparent. They are usually attributed to the possible multi-source structure of the production process and described using a multi-NBD form of the multiplicity distribution. We investigate the possibility of keeping a single NBD but with its parameters depending on the multiplicity N . This is done by modifying the widely known clan model of particle production leading to the NBD form of P (N ). This is then confronted with the approach based on the so-called cascadestochastic formalism which is based on different types of recurrence relations defining P (N ). We demonstrate that a combination of both approaches allows the retrieval of additional valuable information from the multiplicity distributions, namely the oscillatory behavior of the counting statistics apparently visible in the high energy data.

“…The energy dependence of inelasticity is a problem of great interest from both theoretical and experimental standpoints [1]. However, the experimental data are scarce and, on the theoretical side, the existing models are largely in conflict with each other even in explaining a simple aspect as the center-of-mass energy dependence of the inelasticity [2], [3]. For example, the decrease in inelasticity with energy is advocated by some authors, while others believe that the inelasticity is an increasing function of energy [1].…”

We study the impact parameter dependence of inelasticity in the framework of an updated geometrical model for multiplicity distribution. A formula in which the inelasticity is related to the eikonal is obtained. This framework permits a calculation of the multiplicity distributions as well as the inelasticity once the eikonal function is given. Adopting a QCD inspired parametrization for the eikonal, in which the gluon-gluon contribution dominates at high energy and determines the asymptotic behavior of the cross sections, we find that the inelasticity decreases as collision energy is increased. Our results predict the KNO scaling violation observed at LHC energies by CMS Collaboration.
