Study of charge-dependent behavior of final-state particles inπ−pinteractions at 205 GeV/c

Inelastic channels in ..pi../sup -/p interactions at 205 GeV/c are studied as a function of charged-particle multiplicity n/sub ch/. Experimental tests are made which are sensitive to the charge-dependent behavior of the particles, particularly at high and low rapidities. A set of new variables useful for the study of these processes is introduced. Effects which may be attributed to leading particles or leading jets are present to some extent for all n/sub ch/. Among the results presented, it is shown that at this energy there is no ''central region'' which is completely free of effects which are correlated with the charges of the incident particles. Qualitative interpretation of the results in terms of cluster-model ideas is presented; a specific simple model is calculated and compared with the data.
