Abstract
Photons produced in the pre-equilibrium/pre-hydro stage of the quark-gluon plasma produced in relativistic heavy-ion collisions were computed using parton distribution functions obtained from solutions of the Boltzmann equation. The effect of the initial gluon momentum anisotropy and the dependence on the saturation momentum was investigated. We see that small results in a photon yield enhancement, whereas a larger results in a pre-equilibrium photon suppression, owing to the strict constraint of matching to experimental energy density.
