  We quantify the magnitude of the parton energy loss in jets in lead-lead
collisions at the LHC. We extract the effective color factor characterizing the
difference between the in-medium radiation of quark-initiated jets and
gluon-initiated jets from the data. Then, we examine the energy loss of prompt
charmonia and we point to a remarkable similarity between the quenching of
light-quark-initiated jets and the prompt charmonia suppression. Finally, we
discuss possible sources of this similarity.
