  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.
