Abstract
The inclusive production of the neutral vector mesons K0(892) and (1020), and of the tensor meson K02 (1430), in hadronic decays of the Z has been measured by the DELPHI detector at LEP. The average production rates per hadronic Z decay have been determined to be 0.77 +/- 0.08 K0(892), 0.104 +/- 0.008 (1020) and 0.079 +/- 0.040 K02 (1430). The ratio of the tensor-to-vector meson production yields, hK02 (1430) i=hK0(892) i = 0.10 +/- 0.05, is smaller than the hf2(1270)i=h0(770)i and hf02(1525)i =h(1020)i ratios measured by DELPHI. The production rates and differential cross sections are compared with the predictions of JETSET 7.4 tuned to the DELPHI data and of HERWIG 5.8. The 0(892) and (1020) data are compatiblewith model predictions, but a large disagreement is observed for the K02 (1430).
