Interactions between jets and the hot, dense QCD medium

High energy jets provide a valuable tool for the tomographic study of the hot, dense QCD matter created in relativistic heavy ion collisions. With the assumption of weak coupling of hard partons to the medium they traverse, one may compute the medium modification of light and heavy flavor jets using a pQCD factorization and evolution based approach. The effect of the medium on a hard parton is encoded by non-perturbative transport coefficients. The same coefficients also control the pattern of the energy and momentum deposited into the medium by traversing jets. I will present the calculations of both light and heavy flavor jet energy loss, as well as medium's hydrodynamical response to the propagation of weakly coupled fast partons.
