- A measurement is presented of elliptic (v₂) and triangular (v₃) azimuthal anisotropy coefficients for charged particles produced in Pb + Pb collisions at √sNN = 5.02 TeV using a dataset corresponding to an integrated luminosity of 0.44 nb⁻¹ collected with the ATLAS detector at the LHC in 2018. The values of v₂ and v₃ are measured for charged particles over a wide range of transverse momentum (pT), 1–400 GeV, and Pb + Pb collision centrality, 0–60%, using the scalar-product and multiparticle cumulant methods. These methods are sensitive to event-by-event fluctuations and nonflow effects in the measurements of azimuthal anisotropies. Positive values of v₂ are observed up to a pT of approximately 100 GeV from both methods across all centrality intervals. Positive values of v₃ are observed up to approximately 25 GeV using both methods, though the application of the three-subevent technique to the multiparticle cumulant method leads to significant changes at the highest pT. . At high pT (pT ⪆ 10 GeV), charged particles are dominantly from jet fragmentation. These jets, and hence the measurements presented here, are sensitive to the path-length dependence of parton energy loss in the quark-gluon plasma produced in Pb + Pb collisions.
