- The PHENIX experiment at RHIC has measured and ω meson production in p+p, d+Au and Au+Au collisions for GeV at mid-rapidity. Systematic measurements of light vector mesons for several decay channels provide information about properties of the strongly interacting matter produced in relativistic heavy-ion collisions. We present transverse momentum spectra and nuclear modification factors for and ω mesons. Transverse momentum spectra are compared among different decay channels to discuss yield modification which results from mass modification in the hot medium. We compare the nuclear modification factors of various mesons and discuss differences of their suppression patterns.

- 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 information from a new detector available from RHIC Run7 data.

- Directed and elliptic flow of pi(0) - decay photons in 158 A GeV Pb+Pb collisions has been studied near midrapidity in an analysis of data obtained with the photon spectrometer LEDA of the WA98 experiment at the CERN SPS. Preliminary results on the rapidity and transverse momentum dependence of the flow have been obtained for various centrality classes for p(T) > 0.2 GeV/c and 2.3 < y < 2.9. The results are compared with the pion flow.
