We present a new 3+1D resolved model for the initial state of ultrarelativistic Heavy-Ion collisions, based on the �⊥ factorized Color Glass Condensate hybrid approach [1-4]. This new model responds to the need for a rapidity-resolved initial-state Monte Carlo event generator which can deposit the relevant conserved charges (energy, charge and baryon densities) both in the midrapidity and forward/backward regions of the collision.
Based on the IP-Sat model this event-by-event generator computes the phase-space distributions, from where the relevant conserved charges can be computed as moments. In the present work we have included the leading order contributions to the light flavor parton densities. We present relevant observables, such as the eccentricities and flow decorrelation, as tests of this new approach.
