The reaction π−N→KS0KS0π−N′ at 200 GeV/c has been observed with a sensitivity of 450±150 events/μb. The KS0KS0π− system exhibits substantial K*−(890)K0 production. Also produced are f0(1270)π−, f′(1515)π−, and K*−(1430)K0 final states. These resonances occur predominantly at threshold. The diffractive KS0KS0π− cross section is 3.4±1.1 μb. An enhancement near the A3−(1680) is observed in the KS0KS0π− invariant-mass distribution.

We have performed a high-statistics experiment on the reaction π−p→K+K¯0π−n at 8.0 GeV/c. A Dalitz-plot analysis of the K+K¯0π− system finds that the D(1285) is a JPG=1++ state coupling predominantly to a δπ decay channel, while the E(1420) peak consists mostly of a JPG=0−+ wave with a substantial δπ decay mode. There is little evidence of a 1++ resonance at the E mass.
