Measurements of directed, elliptic, and triangular flow of charged hadrons from Cu+Au collisions at sqrt(sNN) = 200 GeV with PHENIX at RHIC

Measurements of anisotropic flow of inclusive charged hadrons and identified +-p, +-K,
p and ¯ p produced at midrapidity in asymmetric Cu+Au collisions at sqrt(sNN) = 200 GeV are
presented. The data were collected by the PHENIX experiment at the Relativistic Heavy
Ion Collider in 2012. The first three Fourier coefficients in the particlesâ azimuthal distributions,
v1, v2, and v3 characterizing directed, elliptic, and triangular flow are studied over
a broad range of transverse momentum and collision centrality. System comparisons are
made with Cu+Cu and Au+Au collisions at the same center-of-mass energy and varying
scaling parameters are used to investigate the effects of the initial geometry. The slopes
of the measured vn distributions are ordered by particle mass as expected in a system with
global flow. The results are well described by viscous hydrodynamics calculations with
shear viscosity over entropy density values close to the quantum minimum.
