abstract = {The Fourier coefficients $\nu_2$ and $\nu_3$ 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, $p_T$ = 1-100 GeV/$c$. The analysis focuses
on $p_T$ > 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 60x\% most central events. The $\nu_2$
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 $p_{T} \thickapprox$
70 GeV/$c$, in all examined centrality classes. The $\nu_3$
coefficient, only measured with the scalar product method,
tends to zero for $p_{T} \gtrsim$ 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.},
