Description
In this talk, we employ new field-theoretical tools to study photons [1] and, for the first time, jets in a non-equilibrium quark-gluon plasma. Jet broadening and photon emission takes place through radiation which is suppressed by repeated and coherent interaction with the medium. We analyze this physics in a medium that is not in thermal equilibrium. This can provide independent means of extracting quark-gluon plasma transport coefficients, such as the shear viscosity, by using jets or photons. Another important application is jet quenching and photon production in the anisotropic plasma [2] created in the early stages of heavy-ion collisions. We present an analyzis of how these probes are affected by such a momentum anisotropy; more specifically we consider the rapidity dependence of photon emission and jet suppression. Finally, we discuss how to extend our work to higher anisotropy where the exponential growth of chromomagnetic fields dominates momentum broadening during radiation.
