Measurement of inclusive K*(0)(892), phi(1020) and K-2*(0)(1430)
production in hadronic Z decays

Αγγλικά

The inclusive production of the neutral vector mesons K-*0(892) and
phi(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
production 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 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
K-*0(892) and phi(1020) data are compatible with model predictions,
but a large disagreement is observed for the K-2(*0)(1430).
