Extracted the vector to pseudoscalar meson production ratio

Abstract

We present results on the production of omega mesons at high transverse momenta in pi^-Be interactions at 515 GeV/c. The data span the kinematic range 3.5 < p_T < 8 GeV/c. We compare the measured cross section with expectations from Monte Carlo QCD generators. The relative yield of omega to pi^0 mesons is used to extract the ratio of vector to pseudoscalar meson production for the first generation of quarks.
