Partial Wave Analysis of KKPI System in D and E/IOTA Region

A partial wave analysis and a Dalitz plot analysis of high-statistics data from reaction ..pi../sup -/p ..-->.. K/sup +/K/sub S/..pi../sup -/n at 8.0 GeV/c show that the D(1285) is a J/sup PG/ = 1/sup + +/ state and the E(1420) a J/sup PG/ = 0/sup - +/ state both with a substantial delta..pi.. decay mode. The 1/sup + +/ K*anti K wave exhibits a rapid rise near threshold but no evidence of a resonance in the E region. The assignment of J/sup PG/ = O/sup - +/ to the E is confirmed from a Dalitz-plot analysis of the reaction pp ..-->.. K/sup +/K/sub S/..pi../sup -/X/sup 0/. 11 refs., 5 figs.
