Abstract/Summary:
In this thesis, the classical field model developed by Krasnitz et al. is used to compute quark and photon production in heavy ion collisions. The first part of the thesis serves as an independent verification of previous results for quark production. To do so, an iterative method is developed to solve the non-linear system of equations that gives the initial condition for the gluonic field. In the second part, the expression giving the photon production rate is simplified using the symmetries and properties of the Color Glass Condensate and McLerran-Venugopalan models. From the two Feynman diagrams that give the leading order contribution, one is much larger than the other. The dominant diagram is given by a continuum spectrum with a very prominent peak superimposed on it.
