Query: Energy dependence of the dijet imbalance in Pb-Pb collisions at 2.76
  ATeV   The appearance of monojets is among the most striking signature of jet
quenching in the context of ultrarelativistic heavy-ion collisions at the Large
Hadron Collider. Experimentally, the asymmetry of back-to-back jets is
quantified in terms of the dijet imbalance distribution by the ATLAS and CMS
collaborations. Recently, the CMS collaboration has also studied the trigger
jet momentum (P_T) dependence of the imbalance in the range between 120 and 500
GeV which is found to decrease with jet P_T. In this work, results from the
in-medium shower code YaJEM are compared with this data set. These results
suggest that the main effects observed in the data are the kinematical
collimation of jets and the increase in the probability to produce more
collimated quark jets with jet P_T, whereas there is no indication for any
non-trivial energy dependence of the shower-medium interaction mechanism
itself. The data furthermore can rule out models in which the jet shape is
collimated due to the medium modification.
