Forward-backward correlations with strange particles in PYTHIA

TL;DR

This paper investigates strange particle production and correlations in proton-proton collisions using PYTHIA8, identifying key processes and the impact of model parameters like multiparton interactions and strangeness suppression.

Contribution

It provides new insights into how PYTHIA's parameters influence strange particle correlations and identifies processes responsible for these effects.

Findings

Strange particle yields are sensitive to PYTHIA parameters.

Forward-backward correlations reveal underlying production mechanisms.

Manipulating PYTHIA processes alters correlation patterns.

Abstract

We present studies of strange particle yields and correlations in $pp$ collisions in the PYTHIA8 event generator by studying forward-backward correlations. Several key processes that give rise to these correlative effects are identified and manipulated to probe the fundamental properties of strange particle emitting sources. The sensitivity of strange particle production and correlations to PYTHIA's multiparton interaction, color reconnection, and explicit strangeness suppression are shown.
