| Abstract: |
The transverse momentum distribution of charged particles formed in Au–Au collisions at Beam Energy Scan (BES) (GeV) is investigated. In addition, spectra of particle at GeV were examined. Tsallis distribution is used to extract the temperature, volume and the entropic index from the experimental results at mid-rapidity and zero chemical potential. We measure some particle ratios like and which are puzzling horn in the experiment and in the thermal model. We conclude that the horn vanished when we used Tsallis distribution, but this does not confirm a solution to the puzzle, which is primarily visible in the experimental results. |
