Measurements of Jet Azimuthal Anisotropies in Pb+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV

This note describes the measurement of azimuthal anisotropies of jets in Pb+Pb collisions with the ATLAS detector at the LHC. The jets are reconstructed with the anti-$k_{T}$ algorithm with the radius parameter R = 0.2. The azimuthal angles of the jets are measured with respect to the second, third...

description This note describes the measurement of azimuthal anisotropies of jets in Pb+Pb collisions with the ATLAS detector at the LHC. The jets are reconstructed with the anti-$k_{T}$ algorithm with the radius parameter R = 0.2. The azimuthal angles of the jets are measured with respect to the second, third and fourth order event planes as measured in the ATLAS forward calorimeters. This measurement is sensitive to the path length dependence of energy loss of the jets as they traverse the hot nuclear matter, the quark-gluon plasma, produced in Pb+Pb collisions at the LHC. The anisotropies, $v_2$, $v_3$, and $v_4$ are measured as a function of the jet transverse momentum and the event centrality. $v_2$ is found to be larger than zero and $v_3$ and $v_4$ are consistent with zero.
