Neutral K*(890) and ρ0 meson production in e+e- annihilation at ;s=29GeV

Abstract:
The production of neutral K*(890) and ρ0 mesons was studied in e+e- annihilation at s=29 GeV using the High Resolution Spectrometer at PEP. Differential cross sections are presented as a function of the scaled energy variable z and compared to π0 and K0 production. The measured multiplicities are 0.84±0.08 ρ{variant}0 mesons and 0.57±0.09 K*0(890) mesons per event for a meson momentum greater than 725 MeV/c. The ratios of vector meson to pseudoscalar meson production for (u,d), s and c quark are compared to predictions of the Lund model. © 1985.
