  The appearance of monojets is among the most striking signature of jet
quenching in the context of ultrarelativistic heavy-ion collisions.
Experimentally, the disappearance of jets has been quantified by the ATLAS and
CMS collaborations in terms of the dijet asymmetry observable A_J. While the
experimental findings initially gave rise to claims that the measured A_J would
challenge the radiative energy loss paradigm, the results of a systematic
investigation of A_J in different models for the medium evolution and for the
shower-medium interaction presented here suggest that the observed properties
of A_J arise fairly generically and independent of specific model assumptions
for a large class of reasonable models. This would imply that rather than
posing a challenge to any particular model, the observable prompts the question
what model dynamics is not compatible with the data.
