Glittering Glasmas

TL;DR

This paper models gluon production from Glasma flux tubes, showing the resulting multiplicity distribution aligns with experimental negative binomial distributions, and introduces the concept of 'Glitter' decay.

Contribution

It provides a theoretical calculation linking Glasma flux tube properties to observed gluon multiplicity distributions, introducing the 'Glitter' decay process.

Findings

Gluon multiplicity distribution matches negative binomial distribution.

Parameter k scales with number of colors and flux tubes.

Distribution approaches Bose-Einstein for single gluon and flux tube.

Abstract

We compute the production of gluons from Glasma color flux tubes. We calculate the probability distribution of gluon multiplicities arising from the distribution of color electric and color magnetic flux tubes found in the Glasma. We show that the result corresponds to the negative binomial probability distribution observed in experiments. The parameter k that characterizes this distribution is proportional to the number of colors N_c^2-1 and to the number of flux tubes. For one gluon color and one flux tube, the multiplicity distribution is close to a Bose-Einstein distribution. We call this decay process "Glitter", a term that is explained below.
