Resonance production in the reactions K-p→ p overlineK0π +π -π - and K-p→ p overlineK0π +π -π -π 0 at 10 GeV/c
Abstract
We present an analysis of resonance production in the reactions K-p→ p overlineK0π +π -π - and K-p→ p overlineK0π +π -π -π 0at 10 GeV/c , performed by a maximum likelihood method. In neither process is any significant non resonant background found. The former reaction is dominated by K *-(890), Δ++(1236) and ϱ0 production and the latter by K *-, Δ++ and ω0. In the second reaction there is no evidence for any ϱ0 production. Two-body intermediate states appear to be negligible, but the three-body states K*-ϱ0p and K *-Δ++π- definitely contribute. A detailed analysis has been performed of the simultaneous resonance production in K -p→ Δ++K *-π- and the predictions of a Veneziano model calculation for this quasi-three-body final state are found to be in good agreement with the experimental results.
