# Multiplicity dependence of strange and multi-strange hadrons in p$-$p, p$-$Pb and Pb$-$Pb collisions at LHC energies using Tsallis-Weibull Formalism

## TL;DR

This study analyzes the transverse momentum spectra of strange and multi-strange hadrons across different collision systems at LHC energies using the Tsallis-Weibull formalism, revealing how parameters vary with multiplicity and indicating collectivity effects.

## Contribution

It applies the Tsallis-Weibull model to describe $p_T$ spectra in p-p, p-Pb, and Pb-Pb collisions, exploring multiplicity dependence of parameters and their relation to collectivity and dynamic effects.

## Key findings

- The distribution fits all multiplicity classes well.
- The $ ext{lambda}$ parameter increases with multiplicity and shows a mass hierarchy.
- The $q$ parameter exceeds one, indicating non-equilibrium emission sources.

## Abstract

The transverse momentum ($p_{T}$) distribution of strange hadrons ($K_{S}^{0}$ and $\Lambda$) and multi-strange hadrons( $\Xi$ and $\Omega$) measured in p$-$p, p$-$Pb, and Pb$-$Pb collisions at LHC energies have been studied for different multiplicity classes using Tsallis-Weibull (or q$-$Weibull)formalism. The distribution describes the measured $p_{T}$ spectra for all multiplicity (or centrality)classes. The multiplicity dependence of the extracted parameters are studied for the mentioned collisions systems. The $\lambda$ parameter was observed to increase systematically with the collision multiplicity and follows a mass hierarchy for all collision system. This characteristic feature indicates that $\lambda$ can be associated to the strength of collectivity for heavy ion collisions. It can also be related to strength of dynamic effects such as multi-partonic interactions and color reconnections which mimic collectivity in smaller systems. The non-extensive $q$ parameter is found to be greater than one for all the particles suggesting that the strange particles are emitted from a source which is not fully equilibrated.
