Partial wave analysis of the K+K̄0π− system produced in the reaction π−p→K+K̄°π−n at 8 GeV/c

We have performed a partial wave analysis of the K+K0Sπ− system produced in the reaction π−p→K+K̄°π−n at 8 GeV/c. We present the results of the analysis of 30,740 events in the mass range 1.24–1.60 GeV/c2, with 0.0≤−t<1.0 GeV2/c2. In the 1.28 GeV/c2 mass region, we see evidence for a JPG=0−+ resonance in addition to the resonant 1++ wave. We observe a 0−+ resonance and possibly a small 1++ resonance in the 1.42 GeV/c2 region. We also observe a 1++ state near 1.5 GeV/c2.
