Abstract
The azimuthal distribution of identified pi(0) and inclusive photons has been measured in root s(NN)=200 GeV Au+Au collisions with the PHENIX experiment at the Relativistic Heavy-Ion Collider (RHIC). The second-harmonic parameter (v(2)) was measured to describe the observed anisotropy of the azimuthal distribution. The measured inclusive photon v(2) is consistent with the value expected for the photons from hadron decay and is also consistent with the lack of direct photon signal over the measured p(T) range 1-6 GeV/c. An attempt is made to extract v(2) of direct photons.
