Partial Wave Analysis of the $K + \bar{K}0 \pi^-$ System

We have performed a partial-wave analysis of the K+KS0π− system produced in the reaction π−p→K+K¯0π−n at 8 GeV/c. We present the results of the analysis of 30740 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.
