Charged multiplicities in pp and AA collisions at LHC

Regular Article - Theoretical Physics

Abstract

The mid-rapidity charged particle multiplicities in pp and AA collisions at LHC energies are described in the framework of a generalized eikonal model with shadowing corrections incorporated in AA. We show that the pp data require a Pomeron intercept close to 1.2, higher than the conventional one, close to 1.1. An s 0.11 energy dependence is obtained in the LHC range and beyond. The size and centrality dependence of the AA multiplicity at \(\sqrt{s} =2.76\ \mathrm{TeV}\) is reproduced and its energy dependence is predicted.
