description | We discuss the transverse momentum broadening of hard probes traversing an evolving glasma, which is the earliest phase of the matter produced in relativistic heavy-ion collisions. The coefficient qˆ is calculated using the Fokker-Planck equation, and an expansion in the proper time τ which is applied to describe the temporal evolution of the glasma. The correlators of the chromodynamic fields that determine the Fokker-Planck collision terms, which in turn provide qˆ, are computed to fifth order in τ. The momentum broadening is shown to rapidly grow in time and reach a magnitude of several GeV2/fm. We show that the transient pre-equilibrium phase provides a contribution to the energy loss of hard probes which is comparable to that of the long lasting, hydrodynamically evolving, equilibrium phase. |
