Investigation of particle distributions in Xe-Xe collision at 5.44 TeV with Tsallis statistics

The distribution characteristic of final-state particles is one of significant parts in high energy nuclear collisions. The transverse momentum distribution of charged particles carries essential evolution information about the collision system. Tsallis statistics is used to investigate the transverse momentum distribution of charged particles produced in Xe-Xe collisions at 5.44 TeV. On the basis, we reproduce the nuclear modification factor of the charged particles. The calculated results agree approximately with the experimental data measured by the ALICE Collaboration.

Multisource thermal model to the transverse momentum spectra in pp collisions at RHIC and LHC energies

In this paper, an improved multi-source thermal model is used to analyze the transverse momentum spectra in $pp$ collisions at high energies ranging from $\sqrt{\mathrm{\it s_{NN}}}$ = 62.4 GeV to 7 TeV. We give a detailed comparison between the theoretical results and experimental data at RHIC and LHC energies. It is shown that the excitation factors of emission sources depend linearly on ln$\sqrt{\mathrm{\it s_{NN}}}$ in the framework. Based on the variation regularity of the source-excitation factors, transverse momentum spectra are predicted in $pp$ collisions at higher energies, potential future $pp$ colliders operating at $\sqrt{\mathrm{\it s_{NN}}}$ = 33 and 100 TeV.

Transverse momentum and pseudorapidity dependence of particle production in Xe-Xe collision at 5.44 TeV

Through the collision-system configuration, the Tsallis statistics is combined with a multisource thermal model. The improved model is used to investigate the transverse momentum and pseudorapidity of particles produced in Xe-Xe collisions at 5.44 TeV. We discuss detailedly the thermodynamic properties, which are taken from the transverse momentum distributions of pion, kaon and proton for different centralities. The pseudorapidity spectra of charged particles for different centralities are described consistently in the model. And, the model result can estimate intuitively the longitudinal configuration of the collision system. PACS numbers: 13.85.-t, 14.40.-n, 12.40.Ee
