Abstract

By taking into account the effects of thermal motion, the transverse momentum distributions of identified charged particles produced in nucleus collisions are discussed in the context of a hydrodynamic model including phase transition. A comparison is made between the theoretical predictions and experimental measurements. The theoretical model gives a good description to the data collected in Au–Au collisions at RHIC energy of [Formula: see text][Formula: see text]GeV. For Pb–Pb collisions at LHC energy of [Formula: see text][Formula: see text]TeV, the model works well up to the transverse momentum of about [Formula: see text][Formula: see text]GeV/c.
