Abstract

The energy dependence of charged-hadron production in proton-proton collisions at RHIC and LHC energies is investigated in a non-equilibrium statistical relativistic diffusion model (RDM) with three sources for particle production. Calculated charged-hadron pseudorapidity distributions for pp at RHIC energies of ##IMG## [http://ej.iop.org/images/0295-5075/95/6/61001/epl13800ieqn1.gif] \sqrt s = 0.2 and 0.41 TeV, and at LHC energies of 0.9, 2.36 and 7 TeV are optimized with respect to the available data. Predictions for 14 TeV are made. The central source arising from gluon-gluon collisions becomes the major origin of particle production at LHC energies. The midrapidity dip is essentially determined by the interplay of the three sources.
