Influence of momentum and charge conservation on azimuthally sensitive correlations

TL;DR

This paper investigates how local conservation laws of charge, baryon number, and momentum influence azimuthal correlations in quark-gluon plasma, using a Markov chain Monte Carlo approach to simulate charge and baryon neutralisation effects.

Contribution

It introduces a novel Monte Carlo method to model local charge, baryon, and momentum conservation effects on azimuthal correlations in high-energy collisions.

Findings

Charge and baryon number neutralisation affect azimuthal correlators.

Local momentum conservation influences azimuthal correlation signals.

The method provides insights into C and CP violation observables.

Abstract

Charge neutralisation procedure based on a Markov chain Monte Carlo algorithm is applied to a system of generated hadrons. The algorithm changes the charge of a randomly picked particle by shifting it within its isomultiplet. For baryons changes in both electric charge and baryon number are applied and the algorithm leads to charge and baryon number neutralisation. The procedure can thus be used to study the effects of the local charge and baryon number conservation. We attempt to study these together with the local momentum conservation and their effect on azimuthal correlator observable sensitive to local C and CP violation in quark-gluon plasma.
