A measurement is presented of elliptic () and triangular () azimuthal anisotropy coefficients for charged particles produced in collisions at using a dataset corresponding to an integrated luminosity of collected with the ATLAS detector at the LHC in 2018. The values of and are measured for charged particles over a wide range of transverse momentum (), 1–400 , and 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 are observed up to a of approximately 100 from both methods across all centrality intervals. Positive values of are observed up to approximately 25 using both methods, though the application of the three-subevent technique to the multiparticle cumulant method leads to significant changes at the highest . At high (), 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 collisions.
