Description
We develop a new approach to the initial state of heavy-ion collisions by extending the weak field approximation of the Color Glass Condensate formalism beyond the boost invariant limit [1]. Our analytical calculation yields surprisingly simple results for the color fields and the field strength tensor of the Glasma produced in the collision. As an explicit check, we demonstrate quantitative agreement with non-perturbative 3+1D lattice simulations in the weak field limit. We further investigate how longitudinal color charge correlations within the nuclei determine the rapidity profile of the transverse pressure of the Glasma and discuss ideas for new 3+1D initial state models using our framework.
