Transverse momentum $p_{\mathrm{T}}$ spectra of strange particles production in different collisions at $\sqrt{s_{NN}}=2.76,5.02,$ and $7$ TeV

Abstract

We analyse the transverse momentum $p_{\mathrm{T}}$ spectra of strange particles \Kslxi produced in $\text{Pb+Pb}$ collision at $\sqrt{s_{NN}}=2.76$ TeV, $\text{p+Pb}$ collision at $\sqrt{s_{NN}}=5.02$ TeV, and $\text{p+p}$ collision at $\sqrt{s_{NN}}=7$ TeV in different multiplicity events measured by the \textit{CMS} experiment at the Large Hadron Collider. The $p_{\mathrm{T}}$ spectra of strange particles are fitted by Tsallis statistics and Boltzmann statistics, respectively. The fitting parameters are studied as a function of the multiplicity events for all systems. The Tsallis temperature ($T_{\mathtt{Ts}}$), Boltzmann temperature ($T_{\mathtt{Boltz}}$), and radius of the system ($R$) increase with both the mass and strangeness number of the particle and also increase with the multiplicity events. The non-extensive parameter ($q$) decreases with the increase in the mass of the particle and also decrease with the increase in the multiplicity events which means that the system tends to thermodynamic stabilization. The extracted temperatures from the two statistics for the strange particles are exhibited a linear correlation.
