Modeling of quantum effects in the hadronization

TL;DR

This paper introduces a quantum-inspired model of hadronization that explores the origins of azimuthal hadron ordering and Bose-Einstein correlations, comparing predictions with experimental data.

Contribution

It implements a quantum effects-based modification to the QCD string fragmentation model to explain hadron correlation phenomena.

Findings

The model reproduces the threshold momentum difference observed in experiments.

Particle decays and polarization significantly influence two-particle correlation measurements.

The study discusses how hadronization impacts long-range angular correlations.

Abstract

A recent observation of a threshold momentum difference in the production of adjacent hadrons is implemented in the fragmentation model of a three-dimensional QCD string, with the aim to investigate the common origin of the azimuthal ordering of hadrons and of the correlations commonly attributed to the Bose-Einstein effect. The role of particle decays and their polarization in the measurement of two-particle correlations is evaluated. A comparison with the available data is presented and further measurements suggested. The impact of the hadronization on the long range angular correlations is discussed.
