# Effect of Rope Hadronisation on Strangeness Enhancement in p$-$p collisions at LHC energies

## TL;DR

This paper investigates how rope hadronization influences strangeness enhancement in high-multiplicity proton-proton collisions at LHC energies, using Pythia8 simulations to replicate experimental observations.

## Contribution

It demonstrates that the microscopic rope hadronization model can successfully describe strangeness enhancement and related phenomena in high-energy p-p collisions.

## Key findings

- Rope hadronization explains strangeness enhancement in high-multiplicity p-p collisions.
- Model reproduces the shape and hardening of $p_T$ spectra with multiplicity.
- Predictions align with experimental data for strange hadron yields at 7 and 13 TeV.

## Abstract

The p$-$p collisions at high multiplicity at LHC show small scale collective effects similar to that observed in heavy ion collisions such as enhanced production of strange and multi-strange hadrons, long range azimuthal correlations, etc. The observation of strangeness enhancement in p$-$p collisions at at $\sqrt{s}$ = 7 TeV and 13 TeV as measured by ALICE experiment is explored using Pythia8 event generator within the framework of microscopic rope hadronization model which assumes the formation of ropes due to overlapping of strings in high multiplicity environment. The transverse momentum ($p_{T}$) spectra shape and its hardening with multiplicity is well described by the model. The mechanism of formation of ropes also described the observed experimental strangeness enhancement for higher multiplicity classes in p$-$p collisions at 7 TeV and 13 TeV. The enhancement with multiplicity is further investigated by studying the mean $p_{T}$ ($<p_{T}>$) and the integrated yields ($<dN/dy>$ ) of strange and multi-strange hadrons and comparing the predictions to the measured data at LHC for 7 TeV and 13 TeV.
