Charged multiplicities in pp and AA collisions at LHC
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 energy dependence is obtained in the LHC range and beyond. The
size and centrality dependence of the AA multiplicity at TeV
is reproduced and its energy dependence is predicted.Comment: 12 pages, 4 figures, 2 tables To be published in EPJ
