摘要
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 root s= 0.2 and 0.41TeV, and at LHC energies of 0.9, 2.36 and 7TeV are optimized with respect to the available data. Predictions for 14TeV 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. open access Copyright (C) EPLA, 2011
