Description
Recent classical-statistical numerical simulations have established the "bottom-up" thermalization scenario of Baier et al. as the correct weak coupling effective theory for thermalization in ultrarelativistic heavy-ion collisions. I will talk on a parametric study of photon production in the various stages of this bottom-up framework and compare the contribution of the off-equilibrium "Glasma" and that of a thermalized Quark-Gluon Plasma. I argue that such Glasma contributions are important and may dominate photon production in peripheral and even semi-central heavy-ion collisions. Furthermore, I will report on first kinetic simulations of photon production in the expanding Glasma that will quantify our estimates and determine how brightly the Glasma shines relative to the Quark-Gluon Plasma.
