  The Fourier coefficients v[2] and v[3] characterizing the anisotropy of the
azimuthal distribution of charged particles produced in PbPb collisions at
sqrt(s[NN]) = 5.02 TeV are measured with data collected by the CMS experiment.
The measurements cover a broad transverse momentum range, 1 < pT < 100 GeV. The
analysis focuses on pT > 10 GeV 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 v[2] coefficient is
measured with the scalar product and the multiparticle cumulant methods, which
have different sensitivities to the initial-state fluctuations. The values of
both methods remain positive up to pT of about 60-80 GeV, in all examined
centrality classes. The v[3] coefficient, only measured with the scalar product
method, tends to zero for pT greater than or equal to 20 GeV. 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.
