Energy dependence of the dijet imbalance in Pb-Pb collisions at 2.76 ATeV

Understand

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.
