Abstract:We study systematically the topological charge density and the chiral density correlations in the early stage of high energy nuclear collisions: the intial condition is given by the McLerran-Venugopalan model and the evolution of the gluon fields is studied via the Classical Yang-Mills equations up to proper time τ ≈ 1 fm/c for an SU (2) evolving Glasma. Topological charge is related to the gauge invariant E • B where E and B denote the color-electric and color-magnetic fields, while the chiral density is prod… Show more
