Beschreibung
We study the impact of the Glasma fields, used to describe the very-early stage of heavy-ion collisions, on the transport of hard probes, namely heavy quarks and jets. We perform numerical simulations of the strong classical fields using techniques from real-time lattice gauge theory. The resulting fields are used as background for the classical transport of ensembles of particles, described by Wong's equations. We develop a numerical solver for the transport of the probes, based on colored particle-in-cell methods.
We focus on the dynamics of heavy quarks and jets in the classical colored fields. To quantify the effect of the Glasma, we extract momentum broadening of hard probes and evaluate the anisotropy transfer from the Glasma to the probes. We investigate other ways to measure the imprint of the Glasma, such as two-particle angular correlations of quark pairs or gauge invariant correlators of color Lorentz forces exerted on the probes.
