Jet Modifications in Early-Stage Heavy-Ion Collisions

This paper investigates how jets, produced in heavy-ion collisions, are affected by the evolving quark-gluon plasma (QGP) during the initial, non-equilibrium stages. It focuses on the jet quenching parameter and elastic collision kernel, crucial for understanding jet-medium interactions. The study improves QCD kinetic theory simulations by incorporating more realistic medium effects and analyzes gluon splitting rates beyond isotropic approximations. The identification of a novel weak-coupling attractor further enhances the modeling of the QGP's evolution and equilibration.
