  We present a method based on three-particle azimuthal correlation cumulants
for the study of the interaction of jets with the medium produced in heavy ion
collisions at RHIC and LHC usable whenever jets cannot be reconstructed on an
event-by-event basis with conventional jet finding algorithms. The method
yields a model independent correlation function which may be used to study jet
structure or search for new phenomena such as conical emission.
