abstract = {The Fourier coefficients v2 and v3 characterizing the
anisotropy of the azimuthal distribution of charged
particles produced in PbPb collisions at sNN=5.02 TeV are
measured with data collected by the CMS experiment. The
measurements cover a broad transverse momentum range,
1<pT<100 GeV/c . The analysis focuses on the pT>10 GeV/c
range, where anisotropic azimuthal distributions should
reflect the path-length dependence of parton energy loss in
the created medium. Results are presented in several bins of
PbPb collision centrality, spanning the $60\%$ most central
events. The v2 coefficient is measured with the scalar
product and the multiparticle cumulant methods, which have
different sensitivities to initial-state fluctuations. The
values from both methods remain positive up to
pT∼60–80 GeV/c , in all examined centrality classes.
The v3 coefficient, only measured with the scalar product
method, tends to zero for pT≳20 GeV/c . Comparisons
between theoretical calculations and data provide new
constraints on the path-length dependence of parton energy
loss in heavy ion collisions and highlight the importance of
the initial-state fluctuations.},
