Understand
Recent LHC results concerning full jet-quenching in PbPb collisions have been presented in terms of a jet asymmetry parameter, measuring the imbalance between the transverse momenta of leading and subleading jets.
- We examine the potential sensitivity of this distribution to fluctuations from the heavy-ion background.
- Our results suggest that a detailed estimate of the true fluctuations would be of benefit in extracting quantitative information about jet quenching.
- We also find that the apparent impact of fluctuations on the jet asymmetry distribution can depend significantly on the choice of low-pt threshold used for the simulation of the hard pp events.
