Effects of jet-medium interactions on angular correlations of jet-particle pairs at different energy scales

International audienceThe energy-loss of hard probes within the hot and dense medium of a quark gluon plasma (QGP) can be described by theoretical model based on radiative energy loss as well as combinations of collisional and radiative energy loss. In a search for observables that allow to disentangle these energy-loss mechanisms, we introduced a set of effective models that allows to investigate the consequences on jets of both types of jet-medium interactions within a consistent framework.We particularly studied angular jet-broadening via angular two-particle correlations.Distinguishing contributions from pairs at different scales of particle momenta, we found qualitative differences between radiative and collisional approaches
