Bose-Einstein correlations and the stochastic scale of light hadrons emitter source

TL;DR

This paper uses quantum field theory at finite temperature to analyze Bose-Einstein correlations among light hadrons, revealing how source size, multiplicity, and temperature depend on particle energy and mass, with implications for collider experiments.

Contribution

It introduces new theoretical results linking BEC parameters to physical properties of the emitting source, including off-correlation between non-identical particles, for the first time.

Findings

Parameters of BEC function depend on particle energy, mass, and temperature.

First theoretical analysis of off-correlation between non-identical hadrons.

Provides a framework for extracting source characteristics from experimental data.

Abstract

Based on quantum field theory at finite temperature we carried out new results for two-particle Bose-Einstein correlation (BEC) function ${C_2}(Q)$ in case of light hadrons. The important parameters of BEC function related to the size of the emitting source, mean multiplicity, stochastic forces range with the particle energy and mass dependence, and the temperature of the source are obtained for the first time. Not only the correlation between identical hadrons are explored but even the off-correlation between non-identical particles are proposed. The correlations of two bosons in 4-momentum space presented in this paper offer useful and instructive complimentary viewpoints to theoretical and experimental works in multiparticle femtoscopy and interferometry measurements at hadron colliders. This paper is the first one to the next opening series of works concerning the searching of BEC with experimental data where the parameters above mentioned will be retrieved.
