Abstract
Preliminary results from the STAR collaboration for the azimuthal elliptic anisotropy (v2) of high transverse momentum (pT) direct photons (γdir) produced at midrapidity (|ηγdir| < 1) in Au+Au collisions at center-of-mass energy = 200 GeV are presented, and compared to the measured (v2) of neutral pions (π0) in the same kinematic range. The electromagnetic transverse shower profile is used to distinguish π0 from direct photons. The measured v2γdir(pT) at high pT (8 < pTγdir < 20 GeV/c) is found to be smaller than that of π0 and consistent with zero when using the forward detectors in determining the event plane.
