Tsallis fits of K^?(892)⁰ and (1020)⁰ mesons in p - Pb collisions

We have reported the production of K*(892)(0) and phi (1020)(0) mesons as a function of pT in the range of 0 < pT < 14 GeV/c and 0 < pT < 20 GeV/c for p - Pb collisions in the rapidity region of -0.5 < y < 0 at ,root sNN = 5.02 and 8.16 GeV, respectively. The pT spectra for K*(892)(0) and phi (1020)(0) mesons are generated by using PYTHIA8 tuned to parton showers (time-like, space-like, VINCIA and DIRE showers). The pT spectra for K*(892)(0) and phi (1020)(0) mesons cannot be produced by time-like showers but give good agreement for remaining showers. Additionally, we also investigated the thermodynamic properties of K*(892)0 and phi (1020)0 mesons in p - Pb collisions extracted through the fitting of the Tsallis distribution function over the ALICE data. A comparison of the pT spectra produced by PYTHIA8 with ALICE data shows some deviations. Also, the ALICE data is used for fitting with the non extensive Tsallis distribution function to extract the effective temperature, T-eff, chemical potential, mu and value of non extensive parameter, q.
