Particle Production in the Central Region at LHC Energies

Abstract

We consider the first LHC data for pp collisions in the framework of Regge phenomenology, and the Quark-Gluon String Model, and we present the corresponding predictions for both the integral cross sections and the inclusive densities of secondaries, that are determined by Pomeron exchange. All parameters were fixed long time ago for the description of the data at fixed target energies. The first measurements of the total inelastic cross section by ATLAS and CMS Collaborations are in agreement with our calculations. Also the inclusive densities measured in the central region are in agreement with our theoretical predictions on the accuracy level of about 10-15%.
