"Momentum broadening in the Glasma";
Talk: Instituto Gallego de Física de Altas Energías (IGFAE) Seminar, Universidade de Santiago de Compostela (invited); 2020-03-25.

Jets created in relativistic heavy-ion collisions provide important information about the whole space-time evolution of the medium. While much work has been done on jets interacting with the hydrodynamic quark-gluon plasma stage, modifications due to short-lived pre-equilibrium stage are usually neglected. In this talk I will present our latest results on jet momentum broadening occurring in the pre-equilibrium Glasma based on the Color Glass Condensate (CGC) framework. I show how we can compute the transverse momentum acquired by a highly energetic colored particle through interactions with the classical color fields in the Glasma in a manifestly gauge-invariant way. We apply these methods semi-analytically to the dilute Glasma and, using real-time lattice gauge simulations, also to the dense Glasma created in heavy-ion collisions. One particularly surprising result is that momentum broadening in the Glasma occurs anisotropically, with more efficient broadening in rapidity compared to azimuthal broadening.
