Measurement of inclusive omega and eta-prime production in hadronic Z decays

We present a study of the inclusive ω and η′ production based on 3.1 million hadronic Z decays recorded with the L3 detector at LEP during 1991–1994. The production rates per hadronic Z decay have been measured to be 1.17±0.17 ω mesons and 0.25±0.04 η′ mesons. The production rates and the differential cross sections have been compared with predictions of the JETSET and the HERWIG Monte Carlo models. We have observed that the differential cross sections can be described by an analytical quantum chromodynamics calculation.

electron positron: colliding beams
electron positron: annihilation
Z0: electroproduction
Z0: hadronic decay
omega(783): hadronic decay
eta(958): hadronic decay
eta(958): radiative decay
rho(770)
yield: (omega(783) eta(958))
