Backward production of a spin-parity 1$^{+}$ Krho resonance at 1.28 GeV
A (K pi pi )/sup +/ mass enhancement is observed in the reactions K /sup -/p to Xi /sup -/K/sup 0+//sub pi //sup +/ pi /sup 0-/ when events with a small (K/sup -/ to Xi /sup -/) four momentum transfer squared are selected. The signal is also visible in the reaction K/sup -/p to Xi /sup -/ pi /sup +/...

| description | A (K pi pi )/sup +/ mass enhancement is observed in the reactions K /sup -/p to Xi /sup -/K/sup 0+//sub pi //sup +/ pi /sup 0-/ when events with a small (K/sup -/ to Xi /sup -/) four momentum transfer squared are selected. The signal is also visible in the reaction K/sup -/p to Xi /sup -/ pi /sup +/+neutrals. The enhancement, centered at 1.28 GeV, is seen to decay preferentially into K rho with spin-parity JP=1/sup +/. The cross section for K/sup -/p to Xi /sup -/C/sup + /(1.28) with C/sup +/ to K rho at 4.15 GeV/c incident K/sup -/ momentum is (6.2+or-0.6) mu b. (11 refs). |
