Nonlinear coupling of flow harmonics: Hexagonal flow and beyond


Higher Fourier harmonics of anisotropic flow (v_4 and beyond) get large contributions induced by elliptic and triangular flow through nonlinear response. In this paper, authors present a general framework of nonlinear hydrodynamic response which encompasses the existing one, and allows to take into account the mutual correlation between the nonlinear couplings affecting Fourier harmonics of any order. They obtain the first experimental measure of the coefficient x_624, which couples v_6 to v_2 and v_4. Also, they argue that within their formalism the nonlinear structure of a given higher harmonic can be determined more accurately than the ha ...
