Abstract
An analysis of a data sample of 1296 events of the reaction pp → K + K −π +π − at 2.32 GeV/ c is presented. The reaction cross section is 300 ± 20 μb. A number of tests of C conservation were made with careful attention to possible systematic errors, yielding no clear evidence of C violation. Various quasi two-body and quasi three-body final states contributing to this reaction were studied. The final state φπ + π − appears to be produced via a Zweig's rule violating mechanism. An analysis of the quasi three-body final state, K ∗0K −π + (with K ∗0→ K +π − ) plus charge conjugate, whose cross section is 84 ± 12 μb, is given. The properties of this final state are compared with expectations based on a simple baryon exchange model, and poor agreement is found. A quark model allows a successful qualitative interpretation of the properties of this three-body final state.
