Using QCD kinetic theory, we study momentum broadening of jets using the full broadening probability (elastic collision kernel) C(q_⊥) extracted during simulations of the nonequilibrium initial stages in heavy-ion collisions. We find that small momentum transfer is more likely than in thermal equilibrium, particularly along the beam axis. Our extraction represents a significant step towards a more realistic modeling of jet quenching during the initial stages.
