The Bose-Einstein Correlations and the strong coupling constant at low energies

TL;DR

This paper demonstrates that Bose-Einstein correlations can be used to determine the strong coupling constant in the non-perturbative regime, aligning with analytic perturbative theory and offering an alternative measure of hadron interactions.

Contribution

It introduces a novel method to extract the strong coupling constant from Bose-Einstein correlations in the non-perturbative energy regime.

Findings

The extracted $\alpha_s(E)$ agrees with analytic perturbative theory.

The method provides a smooth extrapolation to high-energy perturbative $\alpha_s(E)$.

BEC dimension can serve as an alternative measure of short-range hadron interactions.

Abstract

It is shown that $\alpha_s(E)$, the strong coupling constant, can be determined in the non-perturbative regime from Bose-Einstein correlations (BEC). The obtained $\alpha_s(E)$ is in agreement with the prescriptions dealt with in the Analytic Perturbative Theory approach. It also extrapolates smoothly to the standard perturbative $\alpha_s(E)$ at higher energies. Our results indicate that BEC dimension can be considered as an alternative approach to the short range measure between hadrons.
