Description

In this paper, The transverse momentum pT spectra of charged particles produced in PbPb collisions at √sNN = 5.02 TeV were analyzed using a modified Tsallis distribution function.
The ALICE Detector's measurements at the Large Hadron Collider. 0.0 < pT < 20 GeV/c is the
pT range. Ten centrality classes, ranging from 0% to 90% in Pb-Pb, and one pp collision for
reference are the outcome.
In this work, the pT spectra at high pT in heavy ion collisions are modified due to in-medium
energy loss. The pT spectra of charged particles can be described by using the modified Tsallis
distribution function including the final state effects in different pT regions.
In the Tsallis power law distrbution gives excellent description of the hadron spectra in pT
range from 0.2 to 300 GeV/c. The parameter T governing the soft bulk contribution to the
spectra remains almost same over wide range of collision energies. The data/fit shows
deviations from the Tsallis distribution which become more pronounced as the system size
increases. show that the above deviations can be attributed to the transverse flow in low pT
region and to the in-medium energy loss in high pT region
