Abstract
Direct photons are a powerful probe to study the property of quark–gluon plasma (QGP) in high energy heavy-ion collisions. In non-central collisions, the anisotropy of the collision region produces the different pressure gradients and particle density that results in different anisotropy of particle emission, depending on the production processes of photons. Therefore, an azimuthal anisotropy parameter v2 is a powerful tool to explore the source of direct photons. We report on the latest direct photon analysis of the nuclear modification factor in and 62.4 GeV Au + Au collisions, and v2 at high pT in 200 GeV Au + Au collisions at RHIC-PHENIX (Run4). We also present the analysis status, using a larger statistics and better reaction plane... (More)
