Abstract
The production of K+ (892), K*0(892), rho0(770) and omega (783) vecto r mesons in qqBAR events as well as in the gluonic UPSILON (1S) decays and UPSILON(4S) --> BBBAR decays has been studied using the ARGUS det ector. Combining these results with data on pseudoscalar meson, phi me son and baryon production collected with the same detector allow compr ehensive studies of quark and gluon fragmentation. Model independent i nformation on s quark and vector meson suppression (s/u = 0.37 +/- 0.0 4, V/(V+P)pi = 0.21 +/- 0.04 and V/(V+P)K = 0.34 +/- 0.03)) are derive d. The data are compared with predictions from the models Jetset 7.3 a nd UCLA 7.31.
