abstract = {A measurement is presented of elliptic ($v_2$) and
triangular ($v_3$) azimuthal anisotropy coefficients for
charged particles produced in Pb+Pb collisions at
$\sqrt{s_{_\text{NN}}} = 5.02$ 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 $v_2$ and $v_3$ are measured for charged
particles over a wide range of transverse momentum
($p_\text{T}$), 1-400 GeV, and Pb+Pb collision centrality,
0-60\%, using the scalar product and multi-particle cumulant
methods. These methods are sensitive to event-by-event
fluctuations and non-flow effects in the measurements of
azimuthal anisotropies. Positive values of $v_2$ are
observed up to a $p_{\text{T}}$ of approximately 100 GeV
from both methods across all centrality intervals. Positive
values of $v_3$ are observed up to approximately 25 GeV
using both methods, though the application of the
three-subevent technique to the multi-particle cumulant
method leads to significant changes at the highest
$p_{\text{T}}$. At high $p_{\text{T}}$ ($p_{\text{T}}
\gtrapprox 10$ 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.},
