Abstract

Measurements have been made in the OPAL experiment at LEP of the inclusive production of strange vector φ(1020) and K^*(892)⁰ mesons, and the tensor meson K₂ ^*(1430)⁰. The overall production rates per hadronic Z⁰ decay have been determined to be 0.100±0.004_stat.±0.007_syst. φ(1020) mesons, 0.74±0.03_stat.±0.03_syst. K^*(892)⁰ mesons and (for x_E<0.3) 0.19±0.04_stat.±0.06_syst. K₂ ^*(1430)⁰ mesons. The measurements for the vector states update previously published results based on lower statistics, while the K₂ ^*(1430)⁰ rate represents the first direct measurement of a strange tensor state in Z⁰ decay. For the vector states, both the overall production rates and normalised differential cross sections, with respect to the scaled energy variable x_E, have been compared to JETSET and HERWIG predictions. The peak positions in the ζ=ln(1/x_p) distributions have been measured and compared to measurements of other hadron states.
