Description
The properties of the produced matter in a heavy-ion collision can be experimentally studied by measuring the azimuthal anisotropy in the momentum distribution of the produced particles. Quantified by the anisotropic flow coefficients, v_n, and corresponding symmetry planes, psi_n, such anisotropy is expected to reflect the shape of the initial energy density of the collision. We report on the measurement of various flow harmonics, v_n, with multi-particle cumulants, and present the results from a study of the inter-correlation among different order symmetry planes psi_n via multi-particle mixed harmonic correlations. This provides comprehensive experimental information on the fluctuating event-by-event shape of the initial conditions, which is currently among the main sources of large theoretical uncertainties in describing the evolution of the system created in heavy-ion collisions.
