Study of the particle transverse momentum spectra in relativistic heavy ion collisions using the Tsallis statistics

In this work, we have analized the transverse momentum spectra of charged pions produced in Au+Au collisions at different energies using the non-extensive Tsallis distribution. The centrality and rapidity dependence of the non-extensivity parameter, q, is studied. In addition, comparisons with simulated heavy ion collisions data using the UrQMD code will be presented
