TL;DR
This paper presents a phenomenological model of the Glasma, analyzing gluon and quark distributions, entropy, and photon production at RHIC and LHC, highlighting how geometric scaling and the Glasma explain observed features.
Contribution
It introduces a novel phenomenological approach to model the Glasma, focusing on gluon over-occupation, evolution, and photon production mechanisms.
Findings
Estimated quark-to-gluon ratios over time
Predicted entropy production dynamics
Explained photon production features at RHIC and LHC
Abstract
I discuss a phenomenological model for the Glasma. I introduce over occupied distributions for gluons, and compute their time evolution. I use this model to estimate the ratio of quarks to gluons and the entropy production as functions of time. I then discuss photon production at RHIC and LHC, and how geometric scaling and the Glasma might explain generic features of such production.
