Abstract

The PHENIX experiment at RHIC has measured ω and ϕ meson production using di-electron decay mode over a psude-rapidity range of |η| ≤ 0.35 and a transverse momentum range of 0 < p T < 5 GeV/c in proton + proton collisions at \( \sqrt s \) = 200 GeV. The spectra of production cross section as a function of p T for ω and ϕ → e + e − show good agreement with other hadornic decay channels ω → π 0 γ, ω 0 π + π − and ϕ → K + K −, respectively.
