Examination of the species and beam energy dependence of particle spectra using Tsallis statistics

  author={Ming Shao and Li Yi and Zebo Tang and Hongfang Chen and Cheng Li and Zhangbu Xu},
Tsallis statistics was used to investigate the non-Boltzmann distribution of particle spectra and their dependence on particle species and beam energy in the relativistic heavy-ion collisions at SPS and RHIC. Produced particles are assumed to acquire radial flow and be of non-extensive statistics at freeze-out. J/ψ , and the particles containing strangeness were examined separately to study their radial flow and freeze-out. We found that the strange hadrons approach equilibrium quickly from… CONTINUE READING
