The energy-loss of hard probes within the hot and dense medium of a quark\ngluon plasma (QGP) can be described by theoretical models based on radiative\nenergy loss as well as combinations of collisional and radiative energy loss.\nIn a search for observables that allow to disentangle these energy-loss\nmechanisms, we introduced a set of effective models that allows to investigate\nthe consequences on jets of both types of jet-medium interactions within a\nconsistent framework. We particularly studied angular jet-broadening via\nangular two-particle correlations. Distinguishing contributions from pairs at\ndifferent scales of particle momenta, we found qualitative differences between\nradiative and collisional approaches.\n
