| Zusammenfassung: | The sources of particle production in relativistic heavy-ion collisions are investigated from RHIC to LHC energies. Whereas charged-hadron production in the fragmentation sources follows a ln(<i>s<i/><sub><i>NN<i/><sub/>/<i>s<i/><sub>0<sub/>) law, particle production in the mid-rapidity low-<i>x<i/> gluon-gluon source exhibits a much stronger dependence ∝ ln<sup>3<sup/>(<i>s<i/><sub><i>NN<i/><sub/>/<i>s<i/><sub>0<sub/>), and becomes dominant between RHIC and LHC energies. The equilibration of the three sources is investigated in a relativistic diffusion model (RDM). It agrees with the thermal model only for <i>t<i/> → ∞. |
