The inclusive production of the neutral vector mesons K*0(892) and ϕ(1020), and of the tensor meson TeX, 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 K*0(892), 0.104 ± 0.008 ϕ(1020) and TeX. The ratio of the tensor-to-vector meson production yields, TeX, is smaller than the 〈f2(1270)〉/〈ρ0(770)〉 and TeX 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 ϕ(1020) data are compatible with model predictions, but a large disagreement is observed for the TeX.
