Abstract:
About 15 000 K-Φp events have been collected in the CERN Ω′ spectrometer. A partial-wave decomposition of the K-Φ system is performed. The 1+SO+ wave is dominant. The 0-P0+ and 2-P0+ waves are important and show resonant behaviour at ∼ 1.83 GeV (Γ ∼ 0.25 GeV) and ∼ 1.73 GeV (Γ ∼ 0.22 GeV) respectively. The first one can be interpreted as the second radial excitation of the kaon while the second one can be identified as one of the two L mesons.
