Inclusive production of k * (892), ρ 0 , and ω (783) mesons in the ϒ energy region

The production of K * + (892), K * 0 (892), ρ 0 (770) and (783) vector mesons in ρ 0 (770) events as well as in the gluonic ϒ (1S) decays and ρ 0 (770) decays has been studied using the ARGUS detector. Combining these results with data on pseudoscalar meson, ℘ meson and baryon production collected with the same detector allow comprehensive studies of quark and gluon fragmentation. Model independent information on s quark and vector meson suppression (s/u=0.37±0.04,V/(V+P) π=0.21±0.04 andV/(V+P) K =0.34±0.03)) are derived. The data are compared with predictions from the models Jetset 7.3 and UCLA 7.31.
