Abstract We have studied inclusiveΔ ++ (1232),∑ + (1385), and∑ − (1385) baryon resonance production inK − p interactions at 32 GeV/c. The inclusive and topological cross sections are estimated and compared with published results at lower energies. No energy variation of the cross section is observed forΔ ++ (1232) and only a slight decrease is seen in case of∑ ± (1385). The production properties are investigated through longitudinal and transverse momentum distributions. TheΔ ++ (1232) is dominantly produced in the target fragmentation region. The∑ + (1385) is produced both in the target fragmentation region and in the central region, while the∑ − (1385) is predominantly produced in the central region. About 20% of the final state protons are produced via aΔ ++ (1232) decay and about 25% of the Λ produced come from the decay of∑ + (1385) and∑ − (1385).
