Baryon correlations in Pythia

TL;DR

This paper investigates baryon pair angular correlations in PYTHIA8, examining how color reconnection and hadronization affect these correlations, and compares theoretical models with ALICE experimental results.

Contribution

It introduces new insights into the influence of gluons and hadronization mechanisms on baryon correlations, proposing a hypothesis to suppress baryon production in gluon jets.

Findings

Color reconnection models significantly affect baryon angular correlations.

Gluons play a crucial role in baryon production mechanisms.

Proposed hypothesis may explain suppression of baryons in gluon jets.

Abstract

We present the results from our investigation of angular correlations between baryon pairs in the PYTHIA8 event generator. We show how colour reconnection models and hadronization mechanisms influence such angular correlations and in particular address the effect of gluons on the baryon production mechanism in the Lund string fragmentation model. We conclude by discussing the new theoretical ideas in comparison with the ALICE pp collision results for the baryon angular correlations. We propose a hypothesis for suppressing baryons produced in gluon jets and show how that may influence the angular correlations.
