Abstract
Data on the inclusive production of the neutral vector mesons rho(0)(7 70), omega(782), K(0)(892), and phi (1020) in hadronic Z decays recor ded with the ALEPH detector at LEP are presented and compared to Monte Carlo model predictions. Bose-Einstein effects are found to be import ant in extracting a reliable value for the p(0) production rate. An av erage p(0) multiplicity of 1.45 +/- 0.21 per event is obtained. The om ega is detected via its three pion decay mode omega --> pi(+)pi(-)pi(0 ) and has a total rate of 1.07 +/- 0.14 per event. The multiplicity of the K(0) is 0.83 +/- 0.09, whilst that of the phi is 0.122 +/- 0.009 , both measured using their charged decay modes. The measurements prov ide information on the relative production rates of vector and pseudos calar mesons, as well as on the relative probabilities for the product ion of hadrons containing u, d, and s quarks.
