Abstract
- The transverse momentum distribution of charged particles formed in AuAu collisions at Beam Energy Scan (BES) ($\sqrt{S_{NN}}=$ 7.7, 11.5, 19.6, 27, 39 $\hspace{0.05cm} GeV$) is investigated. In addition, $ P_{T}$ spectra of $\Lambda$ particle at $\sqrt{S_{NN}}$=62.4 $\hspace{0.03cm} GeV$ was 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 $ \frac{k^{+}}{\pi^{+}} $ and $ \frac{\Lambda}{\pi^{-}} $ 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.
