Query: Jets in medium - what RHIC and LHC measurements of R_AA and I_AA can
  teach about the parton-medium interaction   High P_T observables associated with hard pQCD processes are regarded as
tomographic probes of the medium created in ultrarelativistic heavy-ion
collisions. Unfortunately, tomography is unexpectedly complicated in practice
due to model uncertainties and the highly averaged nature of many observables.
However, a systematic comparison study demanding a simultaneous description of
many observables within the same framework is sufficiently powerful to rule out
a large fraction of conjectured models about the physics mechanism of
parton-medium interaction. From this study, it can be inferred that the
relevant mechanism is likely to be perturbatively tractable medium-induced
radiation with a small component of elastic energy transfer into the medium.
