Abstract

We have reported the production of \(K^{*}(892)^{0}\) and \(\phi (1020)^{0}\) mesons as a function of \(p_{T}\) in the range of \(0< p_{ T} < 14\) GeV/c and \(0< p_{ T} < 20\) GeV/c for \(p-Pb\) collisions in the rapidity region of \(-0.5< y < 0\) at \(\sqrt{s_{NN}}=5.02\) and 8.16 GeV, respectively. The \(p_{T}\) 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 \(p_{T}\) 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 \(p_{T}\) 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.
