# Strangeness Enhancement in p+p, p+Pb and Pb+Pb Collisions at LHC Energies

## TL;DR

This paper explores the possible formation of quark-gluon plasma in small collision systems at LHC energies by analyzing hadron yields and their ratios, developing a dynamical model that aligns with experimental data.

## Contribution

It introduces a dynamical core-corona initialization framework to describe strangeness enhancement in small systems, suggesting QGP formation in high multiplicity events.

## Key findings

- The model reproduces the ALICE data trends for multi-strange hadrons.
- QGP formation is indicated in high multiplicity p+p and p+Pb collisions.
- Strangeness enhancement occurs even in small colliding systems.

## Abstract

We investigate whether the quark gluon plasma (QGP) is created in small colliding systems from analyses of various hadron yields and their ratios in proton-proton (p+p), proton-lead (p+Pb) and lead-lead (Pb+Pb) collisions at LHC energies. Recently, the ALICE Collaboration reports enhancement of yield ratio of multi-strange hadrons to charged pions as a function of multiplicity at mid-rapidity. Motivated by these results, we develop the dynamical core-corona initialization framework and find that our results describe tendencies of the ALICE data especially for multi-strange hadrons. These results indicate that the QGP is partly formed in high multiplicity events in small colliding systems.
