Freeze-out of Strange Hadron in pp, pPb and PbPb Collisions at LHC Energies

TL;DR

This paper analyzes the transverse momentum spectra of strange hadrons in pp, pPb, and PbPb collisions at LHC energies using a modified Tsallis distribution to understand freeze-out conditions across different systems.

Contribution

It introduces a systematic analysis of strange hadron spectra with a modified Tsallis distribution including transverse flow, across multiple collision systems at LHC energies.

Findings

Parameters vary with system size and multiplicity

Transverse flow increases from pp to PbPb collisions

Freeze-out conditions differ across collision types

Abstract

In this article, we will present a systematic analysis of transverse momentum spectra of the strange hadron in different multiplicity events produced in pp collision at $\sqrt{s}$ = 7 TeV, pPb collision at $\sqrt{s_{NN}}$ = 5.02 TeV and PbPb collision at $\sqrt{s_{NN}}$ = 2.76 TeV. The differential freeze out scenario of strange hadron $K^{0}_{s}$ assumed while analyzing the data using a Tsallis distribution which is modified to include transverse flow. The $p_{T}$ distributions of strange hadron in different systems are characterized in terms of the parameters namely, Tsallis temperature ($T$), power ($n$) and average transverse flow velocity ($\beta$).
