When describing the early stages of heavy ion collisions, the incoming nuclei are usually assumed to be Lorentz-contracted to infinitely thin "pancakes". This leads to boost-invariance of the produced glasma-state and reduces the system to effectively 2+1 dimensions. This assumption is less justified at lower collision energies. In a recent work [1] we showed how to allow for a finite pancake thickness in the simulation of the production of a glasma state within the McLerran-Venugopalan model. This is achieved by using the colored particle-in-cell (CPIC) method in the laboratory frame. We verify that this method agrees with boost-invariant approaches for thin nuclei and find deviations in observables like the pressure anisotropy for thicker nuclei.
