A Partial Wave Analysis of the ($\bar{K}0 \pi^+ \pi^-$) System Produced in $K^- p \to \bar{K}0 \pi^+ \pi^- n$ at 10-{GeV}/$c$

Abstract A partial wave analysis of the non-diffractively produced ( K 0 π + π - system has been performed. The system was produced in the reaction K - p→ K 0 π + π - n at 10 GeV/c, measured in the CERN Omega spectrometer. Besides the well-known K∗(1420) resonance, we find good evidence for the production of Q2(1400) and some indication for Q1(1290) production in JP=1+. In addition we clearly observe a bump in the 1800 MeV region, the properties of which are discussed.
