Momentum broadening of energetic partons in an anisotropic plasma

The quark-gluon plasma produced in heavy-ion collisions is anisotropic throughout its evolution. This anisotropy changes the physics of jet-medium interaction, making it dependent on momentum direction jet. In this paper we analyze transverse broadening a jet parton interacting with soft gluons an plasma. Our analysis equally applies to quasiparticles kinetic theory. We subtract contribution from instability modes deep infrared and discuss how our calculation should be complemented that regime. resulting collision kernel for qualitatively different equilibrium isotropic ansatz used effective Because increased medium screening, there substantially less at low intermediate momenta.
