Inclusive Σ^±(1385) production in K^-p interactions at 110 GeV/c

Abstract

Results are presented on inclusive production of ∑⁺(1385) and ∑^-(1385) in K ^- p interactions at 110 GeV/c. The inclusive and topological cross sections have been estimated and compared with published results at lower energies. The inclusive cross section of ∑⁺(1385) seems to decrease with c.m. energy, while that of the ∑^-(1385) is nearly constant. The mean charged multiplicity associate to ∑(1385) increases with c.m. energy. The ∑⁺(1385) is produced both in the target fragmentation region and in the central region where ∑^-(1385) is predominantly produced in the central region. Approximately 16% of the Λ's stem from the decay of ∑^±(1385) and the kinematic distributions of these Λ's are not very different from the inclusive Λ's.
