Photon production from non-equilibrium disoriented chiral condensates in a longitudinal expansion : A theoretic framework

High Energy Physics - Phenomenology 2015-05-28 v1

Abstract

A theoretical framework is developed for treating the quantization of the photons in a spacetime with a longitudinal expansion. This can be used to study the production of the photons through the non-equilibrium relaxation of a disoriented chiral condensate presumably formed in the expanding hot central region in ultra-relativistic heavy-ion collisions. These photons can be a signature of the formation of disoriented chiral condensates in the direct photon measurements of heavy-ion collisions.
