Abstract

We have performed a partial-wave analysis of the reaction $K^{-} p \to K_{S}^{0} π^{+} π^{-} n$ at 6 GeV/c. We present the results of the analysis of about 4500 events in the low- $t$ region ( $| t^{'} | < 0.2$ Ge $V^{2}$ ) for the dominant waves in the 1200-to-2000-MeV mass range. We observe the $2^{+}$ $K^{*} (1430)$ and clear signals for the $1^{+}$ $Q_{2} (1400)$ and the $3^{-}$ $K^{*} (1800)$ . We find a new $1^{-}$ resonance at about 1500 MeV and have some evidence for another $1^{-}$ resonance at 1800 MeV. We also present the results of a partial-wave analysis as a function of $t$ in the 1430-MeV mass region.
