First measurement of the omega-meson production at RHIC by PHENIX
  The PHENIX experiment at RHIC measured the omega-meson production in the range of pT from 2.5 GeV/c to 9.5 GeV/c in p+p and d+Au collision systems at sqrt{s_{NN}}=200 GeV. We present the consistent results of two independent measurements in decay channels omega-->pi^{0}pi^{+}pi^{-}$ and omega-->pi^{0}gamma. The omega/pi^{0} ratio was found to be 0.90+/-0.06. The Nuclear Modification Factor R_{dA} is 1.3+/-0.2 both in the Minimum Biased and (0%-20%) central event samples. The mass of the omega-meson was measured to be consistent with the PDG value within the errors of the measurement. We also measured the K_{S}^{0}-meson production in K_{S}^{0}-->pi^{0}pi^{0} in the same collision systems.
