A Phenomenological Model of the Glasma and Photon Production

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.
