Dependence of related parameters on centrality and mass in a new treatment for transverse momentum spectra in high energy collisions

We collected the experimental data of transverse momentum spectra of identified particles produced in proton–proton (p–p), deuteron-gold (d–Au or d–A), gold–gold (Au–Au or A–A), proton–lead (p–Pb or p–A), and lead–lead (Pb–Pb or A–A) collisions measured by the ALICE, CMS, LHCb, NA49, NA61/SHINE, PHENIX, and STAR Collaborations at different center-of-mass energies. The multisource thermal model at the quark level or the participant quark model is used to describe the experimental data. The free parameters, the effective temperature T, entropy-related index n, and revised index a${}_0$, in the revised Tsallis–Pareto-type function are extracted at the quark level. In most cases, T and n in central collisions are larger than those in peripheral collisions, and a${}_0$ does not change in different centrality classes. With the increase in the mass of the produced particle or participant quark, T and a${}_0$ increase, and n does not change significantly. The behaviors of related parameters from p–p, p(d)–A, and A–A collisions are similar.
