ABSTRACT
Flow harmonics (vn) of the Fourier expansion for azimuthal distributions hadrons are commonly employed to quantify anisotropy particle production relative collision symmetry planes. While lower order coefficients (v2 and v3) more directly related corresponding eccentricities initial state, higher-order flow (vn>3) can be induced by a mode-coupled response lower-order anisotropies, in addition linear same-order anisotropies. These their contributions used precisely constrain conditions transport properties medium theoretical models. The multiparticle cumulant method is measure anisotropic flow, coefficients, correlations event plane angles charged particles as functions centrality transverse momentum Au+Au collisions at nucleon-nucleon center-of-mass energy sNN= 200 GeV. results compared similar LHC measurements well several viscous hydrodynamic calculations with varying conditions.
