Study of the quasi-two body processes including Σ(1385) production in π-p and K-p reactions at 4 GeV/c

An analysis of (1385) production in reactions of the type 0+ 1/z 4 +→>-1+ 3+/2 and 0- + 1/2+→ 0- + 3*/2 is presented. A determination of the Σ(1385) production parameters Is performed and the results are compared with the predictions from several models. A transversity amplitudes reconstruction describing the processes π p ->K(890) Σ(1385) and K-p → 3→φ(1385), ζ-Σ(1385) is obtained in a model independent way. We observe dominance of unnatural partly exchange in the production mechanisms. Exchanges of exotic quantum numbers are established by the study of πp → K0+ Σ(1385)s and K- p→>π+Σ(1385)± processes. Additive quark model predictions are reasonable agreement with the experimental data. (Author)
