Title: Measurement of Leptonic and Hadronic Decays of omega- and phi-Mesons at RHIC by PHENIX

Abstract

The PHENIX experiment at RHIC has measured production of {omega}- and {phi}-mesons in p + p, d + Au and Au+Au collisions at {radical}s{sub NN}=62.4 and 200 GeV. Transverse momentum (mass) spectra measured in hadronic and di-electron decay channels are found to be in agreement with each other within the errors. Nuclear modification factors R{sub AA} measured for both mesons are consistent with results obtained for other neutral mesons. The position of the meson mass peaks and their widths reconstructed in hadronic decay channels are in agreement with their properties measured in vacuum.
