Abstract

The inclusive production of Σ±(1385) is studied in pp interactions at 12 and 24 GeV/c. In this energy range, the inclusive cross sections for Σ+(1385) and Σ(1385) rise from 0.20 ± 0.03 mb to 0.28 ± 0.03 mb and from 0.07 ± 0.02 mb to 0.12 ± 0.02 mb. The decays of Σ±(1385) account for ∼20% of all observed Λ hyperons. The pT2 distributions are compatible with an exponential decrease and the slopes are in agreement with a common value of B ∼ 3 (GeV/c)−2. The longitudinal spectra are significantly different: Σ(1385) is mainly produced in the central region, whereas proton fragmentation contributes strongly to Σ+(1385) production.
