摘要：

We study the gluon distribution in nucleus-nucleus collisions in the framework of the Color Glass Condensate. Approximate analytical solutions are compared to numerical solutions of the nonlinear Yang-Mills equations We find that the full numerical solution can be well approximated by taking the full initial condition of the fields in Coulomb gauge and using a linearized solution for the time evolution We also compare k(T)-factorized approximations to the full solution.
