Abstract

The production of K*+(892), K*0(892), ρ0(770) and ω(783) vector mesons in ρ0(770) events as well as in the gluonic Υ(1 S) decays and ρ0(770) decays has been studied using the ARGUS detector. Combining these results with data on pseudoscalar meson, φ{symbol} 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 and V/(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.
