Abstract
The inclusive production of the neutral vector mesons K-0(892) and ph i(1020), and of the tensor meson K-2(0)(1430), in hadronic decays of the Z has been mea sured by the DELPHI detector at LEP. The average pr oduction rates per hadronic Z decay have been determined to be 0.77 +/ - 0.08 K-2(0)(892), 0.104 +/- 0.008 phi(1020) and 0.079 +/- 0.040 K-2 (0)(1430). The ratio of the tensor-to-vector meson production yields, [K-2(0)(1430)]/[K-*0(892)] = 0.10 +/- 0.05, is smaller than the [f(2 )(1270)]/[rho(0)(770)] and [f'(2)(1525)]/[phi(1020)] ratios measured b y DELPHI. The production rates and differential cross sections are com pared with the predictions of JETSET 7.4 tuned to the DELPHI data and of HERWIG 5.8. The K-0(892) and phi(1020) data are compatible with mo del predictions, but a large disagreement is observed for the K-2(0)( 1430).
