Abstract:
A study of inclusive production of the meson resonances rho0, K*0 (892), f0(975) and f2(1270) in hadronic decays of the Z0 is presented. The measured mean meson multiplicity per hadronic event is 0.83 +/- 0.14 for the rho0, 0.64 +/- 0.24 for the K*0(892). 0.10 +/- 0.04 for the f0(975) in the momentum range p > 0.05p(beam) (x(p) > 0.05) and 0.11 +/- 0.05 for the f2 (1270) for x(p) > 0. 1. These values and the corresponding differential cross sections (1/sigma(hadr)) dsigma/dx(p) for the vector mesons are in good agreement with the predictions of the JETSET 7.3 PS and HFRWIG 5.4 models. The f2 (1270) production is overestimated by HERWIG but its x(p)-shape is correctly reproduced. The measured ratios of the production cross sections sigma (f2(1270))/sigma(rho0) = 0.22 +/- 0.08 and sigma(f2(1270))/sigma(f0(975)) = 3(-1)+7 for x(p) > 0.1 are consistent with the results obtained in hadronic reactions.
