abstract
We study the diffusion of charm and beauty in the early stage of high energy nuclear collisions at RHIC and LHC energies, considering the interaction of these heavy quarks with the evolving Glasma by means of the Wong equations. In comparison with previous works, we add the longitudinal expansion as well as we estimate the effect of energy loss due to gluon radiation. We find that heavy quarks diffuse in the strong transverse color fields in the very early stage (0.2-0.3 fm/c) and this leads to a suppression at low $p_T$ and enhancement at intermediate low $p_T$. The shape of the observed nuclear suppression factor obtained within our calculations is in qualitative agreement with the experimental results of the same quantity for $D-$mesons in proton-nucleus collisions. We compute the nuclear suppression factor in nucleus-nucleus collisions as well, for both charm and beauty, finding a substantial impact of the evolving Glasma phase on these, suggesting that initialization of heavy quarks spectra in the quark-gluon plasma phase should not neglect the early evolution in the strong gluon fields.

Covariant equations of motion of massive spinning particles in a background Yang-Mills field
A spinning quark in a background Yang-Mills field obeys a new, constraint-preserving, gauge-invariant set of classical equations of motion that reduce to the Wong equations when spin effects are turned off.

Entropy from decoherence: a case study using glasma-based occupation numbers
Decoherence of a glasma-like coherent state yields an entropy per particle below the thermal gluon gas value, except in proton-nucleus collisions at small g mu.
