• STATISTICAL-MECHANICS

By assuming the existence of memory effects and long-range interactions, nonextensive statistics together with relativistic hydrodynamics including phase transition are used to discuss the transverse momentum distributions of charged particles produced in heavy ion collisions. It is shown that the combined contributions from nonextensive statistics and hydrodynamics can give a good description of the experimental data in Au+Au collisions at root S-NN = 200 GeV and in Pb+Pb collisions at root S-NN = 2.76 TeV for pi(+/-) and K-+/- in the whole measured transverse momentum region and for p((p)over-bar) in the region of p(T) <= 2.0 GeV/c. This is different from our previous work using the conventional statistics plus hydrodynamics, where the describable region is only limited in p(T) <= 1.1 GeV/c.
