Heavy ion collisions are a topic of intense research due to the fact that is is one of the few situations in nature where a Quark Gluon Plasma (QGP) can form. Theoretical studies of these are complicated by the fact that at various stages of the process different physical phenomenon take over and dominate. In order to fully understand heavy ion collisions one must have a detail understanding of the early time dynamics. We model these initial conditions by using the saturation/Color Glass Condensate framework, which takes into account the initial high energy scattering. While this formalism has been used to calculate the initial gluon distributions to reasonable success we are currently expanding this to include the initial distribution of quarks and anti-quarks with the overall goal of being able to incorporate these into the initial conditions as well. Using these improved initial conditions we hope to be able to calculate various observables in a consistent manner, such as correlations between hadrons and charge dependence.
