PHENIX Measurements of Higher-order Flow Harmonics for Identified Charged Hadrons in Au + Au collisions at image

The azimuthal anisotropy coefficients image, characterizing collective flow in Au + Au collisions, are presented for identified particle species as a function of transverse momentum image, centrality (cent) and beam collision energy image. The image values for each particle species, show little, if any, change over the measured beam energy range, and image vs. image scales to a single curve (constituent quark number image scaling) for each n, over a broad range of transverse kinetic energies image. A comparison of image for individual particle species obtained in Au + Au collisions at image (RHIC) and Pb + Pb collisions at image (LHC), indicate stronger collective flow at the LHC. These flow measurements and their scaling patterns, can provide important additional constraints for extraction of the specific viscosity image.
