Abstract
A (Kππ + mass enhancement is observed in the reactions K- p → Ξ −K0+ π+ π0- when events with a small (K- → Ξ- ) four momentum transfer squared are selected. The signal is also visible in the reaction K- p → Ξ- π+ + neutrals. The enhancement, centered at 1.28 GeV, is seen to decay preferentially into Kϱ with spin-parity JP = 1+. The cross section for K- p→ Ξ−C+ (1.28) with C+ → K ϱ at 4.15 GeV/c incident K- momentum is (6.2 ± 0.6) μb.
