Description

All anti pp events at 22.4 GeV/c were separated into nonannihilation (N-group) and enriched annihilation (A-group) events. The mean sphericity value for the A-sample is in accordance with e+e-, K-p and π-p data. The experimental value of for events from the A-sample is larger than the value for N-events for all multiplicities. Mean charge transfer is found to be very sensitive to the dynamics of the process. The experimental value of mean charge transfer is <ΔQ> = -0.25 if possible particle misidentification is taken into account. The experimental data are compared with the quark-parton model predictions. (orig.)
