Abstract
A partial-wave analysis of the K 0π +π − system from the reaction K − p → K 0π + π − n has been carried out using data obtained at 8.25 GeV/ c in a high-statistics experiment. A strong signal appears in the 1 +SO + (K ∗π) wave at the Q 2 mass (≈ 1.4 GeV). The 1 +S0 + (ϱK) wave behaves rather like a background and does not exhibit the characteristics of a resonance. A prominent signal also appears in the 2 +D wave (via K ∗π and ϱK); it is interpreted as the K ∗(1430). In the L region (1.6–2.1) GeV, there is evidence for the 3 −K ∗(1780) while the 2 − wave also gives some contribution. A strong signal shows up in the 1 − P0−(K ∗π) wave around 1.47 GeV; it does not seem to be due to a resonance. The 0 − S0 + (κπ) wave gives a large contribution in the 1–2 GeV region, but it cannot be identified with the resonating 0 − S0 + (ε K) or 0 − P0 + ( K ∗π) waves observed in diffractive channels.
