Abstract

Anisotropic flow coefficients, v<inf>n</inf>, non-linear flow mode coefficients, χ<inf>n,mk</inf>, and correlations among different symmetry planes, ρ<inf>n,mk</inf> are measured in Pb-Pb collisions at sNN = 5.02 TeV. Results obtained with multi-particle correlations are reported for the transverse momentum interval 0.2 < p<inf>T</inf>< 5.0 GeV/c within the pseudorapidity interval 0.4 < |η| < 0.8 as a function of collision centrality. The v<inf>n</inf> coefficients and χ<inf>n,mk</inf> and ρ<inf>n,mk</inf> are presented up to the ninth and seventh harmonic order, respectively. Calculations suggest that the correlations measured in different symmetry planes and the non-linear flow mode coefficients are dependent on the shear and bulk viscosity to entropy ratios of the medium created in heavy-ion collisions. The comparison between these measurements and those at lower energies and calculations from hydrodynamic models places strong constraints on the initial conditions and transport properties of the system.
