Abstract

We analyze transverse momentum spectra of and at midrapidity in + Au, Cu + Cu, and collisions at  GeV in the formworks of Tsallis statistics and Boltzmann statistics, respectively. Both of them can describe the transverse momentum spectra and extract the thermodynamics parameters of matter evolution in the collisions. The parameters are helpful for us to understand the thermodynamics factors of the particle production.
