摘要

We have attempted to describe the rapidity and transverse momentum spectra, simultaneously, of the hadrons produced in the ultra-relativistic nuclear collisions. We have tried to achieve this in a single statistical thermal freeze-out model using a single set of parameters. We assume the existence of a hadronic gas in thermo-chemical equilibrium at the final hydrodynamic freeze-out. The model incorporates a longitudinal as well as a transverse hydrodynamic flow. We have also found that the role of heavier hadronic resonance decay is important in explaining the particle's rapidity spectra, while the transverse momentum spectra are not affected.
