Initial State Characteristics of Proton--Nucleus and Nucleus--Nucleus Collisions from Glauber Monte Carlo

With a prescribed Coulomb-type energy-momentum tensor, an exact solution of the Einstein field equations over a nonsimply-connected manifold is presented.This spherically symmetric solution has neither curvature singularities nor closed timelike curves.It can be considered to be a regularization of the singular Reissner-Nordström solution over a simplyconnected manifold.
