Bose-Einstein enhancement in the evolution of the double parton densities at high energy

TL;DR

This paper investigates how Bose-Einstein correlations among identical gluons influence the evolution of double parton densities at high energies, revealing faster growth and alignment with experimental data.

Contribution

It introduces Bose-Einstein correlations into the evolution equations for double parton densities at low x, showing their impact on growth rates and momentum scales.

Findings

Double parton densities grow faster with Bose-Einstein correlations.

The typical momentum scale matches the hard scales and saturation momentum.

Results agree with recent experimental observations.

Abstract

In the paper we include Bose-Einsten correlations for identical gluons, in the evolution of the double parton densities at low $x$ (high energies). We show that these correlations result in a faster increase of the double densities, in comparison with the product of two single parton densities. In addition, we find that the typical momentum in the double parton cross section, is of the order of the hard scales in the process, including the saturation momentum. This result is in agreement with recently published experimental data.
