We present measurements of the azimuthal dependence of charged jet production in central and semicentral
√sNN = 2.76 TeV Pb–Pb collisions with respect to the second harmonic event plane, quantified
as vch jet
2 . Jet finding is performed employing the anti-kT algorithm with a resolution parameter R = 0.2
using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of
the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region
fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane
orientations independently. Significant non-zero vch jet
2 is observed in semi-central collisions (30–50%
centrality) for 20 < pch jet
T < 90 GeV/c. The azimuthal dependence of the charged jet production is similar
to the dependence observed for jets comprising both charged and neutral fragments, and compatible with
measurements of the v2 of single charged particles at high pT. Good agreement between the data and
predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a
dense QCD medium, is found in semi-central collisions.
