This proceeding reports on the ATLAS measuremnt of v2 and v3 flow coefficients for charged particles produced in Pb+Pb collisions at √sNN = 5.02 TeV collected with the ATLAS detector at the LHC. The v2 and v3 are obtained for high pT, 1-400 GeV/c and in the centrality range 0–60%. Two methods, the scalar product and multi-particle cumulants, were used to probe the sensitivity to event-by-event fluctuations and non-flow effects. Positive values of v2 and v3 are observed up to a pT ≃ 100 GeV/c and 25 GeV/c respectively. As jets are the primary source of high pT particles, the measurement is sensitive to jets' interaction with QGP and in particular to the jets' QGP path-dependent energy loss.
