Description
In this work, we simulate $SU(3)$ color fields that
occur in the very early stages of
high-energy nuclear
collisions, using classical real-time lattice gauge theory. In particular, we model the structure of the proton and the longitudinal initial state fluctuations to simulate realistic non-boost invariant proton-nucleus collisions. We study the anisotropic momentum, and angular momentum, diffusion of heavy quarks in this stage.
We find that the boost-invariant system retains a large amount of anisotropy even for values of the
proper time which are
quite larger than the typical timescale
of the problem, namely the inverse saturation scale
$\tau=1/Q_s$. Moreover, we find that the inclusion of rapidity-dependent fluctuations leads to a partial tendency to isotropization of the system, and the amount
of isotropization increases with increasing magnitudes of such fluctuations.
