Low Mass Vector Meson Measurements via Di-electrons at RHIC by the PHENIX Experiment

Abstract

The PHENIX experiment at RHIC has measured $\omega$ and $\varphi$ mesons in $p+p$, $d+Au$ and $Au+Au$ collisions at \sqn = 200 GeV via both hadronic and di-electron decay channels. The transverse momentum spectra as measured in different decay modes and at different centralities are shown and discussed here.
