Measurement of Identified {pi}{sup 0} and Inclusive Photon Second-Harmonic Parameter v{sub 2} and Implications for Direct Photon Production in {radical}(s{sub NN})=200 GeV Au+Au

The azimuthal distribution of identified {pi}{sup 0} and inclusive photons has been measured in {radical}(s{sub NN})=200 GeV Au+Au collisions with the PHENIX experiment at the Relativistic Heavy-Ion Collider (RHIC). The second-harmonic parameter (v{sub 2}) was measured to describe the observed anisotropy of the azimuthal distribution. The measured inclusive photon v{sub 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{sub T} range 1-6 GeV/c. An attempt is made to extract v{sub 2} of direct photons.
