Measurement of identified pi0 and inclusive photon v2 and implication to the direct photon production in sqrt(sNN) = 200 GeV Au+Au collisions
PHENIX Collaboration, S. S. Adler
Abstract
The azimuthal distribution of identified pi0 and inclusive photons has been measured in sqrtsNN = 200 GeV Au+Au collisions with the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC). The second harmonic parameter (v2) was measured to describe the observed anisotropy of the azimuthal distribution. The measured inclusive photon v2 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 pT range 1-6 GeV/c. An attempt is made to extract v2 of direct photons.
