Description

We aim to probe the early stages of high-energy nuclear collisions using heavy quarks (HQs). The pre-equilibrium stage of relativistic heavy-ion collisions, commonly known as Glasma, evolves according to the classical Yang-Mills (CYM) equations. We study the transverse momentum broadening $\sigma_p$ of HQs in the evolving Glasma using relativistic kinetic theory. We observe that $\sigma_p \propto t^2$. This is explained as the memory effect present in the gluon fields. Furthermore, we put some interesting results for the comparison of the diffusion of HQs in the evolving Glasma with that of the standard Langevin dynamics. We find that for a small saturation scale, $Q_s$, $\sigma_p$ for the two systems is approximately the same, while significant quantitative differences appear for large $Q_s$.
