Description
We present results from the study of multikaon final states in the reactions π-p→K0K+-π-+X, K0K+K-X at 50 and 100 GeV/c. Here X is semi-inclusive, that is, a specific forward topology and an interaction registering in the counters surrounding the target are required. The D(1285) meson is seen in the deltaπ mode, while the E(1420) meson is observed in both the deltaπ and the K*K modes. In addition, there are two possible enhancements in the three-kaon final state. The first (Mapprox.1840 MeV) is associated with the K0phi mode and is consistent with being the charmed D0. The second, a K* state (M=2003 +- 14 MeV, GAMMA=87 +- 43 MeV), decays into KA2
