New Data on the Reactions K- p --> anti-K0 n and K- p --> K- p Between 1.934-GeV/c and 2.516-GeV/c, Partial Wave Analysis of These Channels and SU(3) Classification of the New Y* States Observed

New data on the K−p elastic and charge exchange reactions are presented in the K− momentum range between 1.934 GeV/c and 2.516 GeV/c. A conventional energy-dependent partial-wave analysis covering the widerPK- range from 1.6 GeV/c to 2.516 GeV/c is presented together with a p.w.a. in which the duality ands-helicity conservation ideas are explicitly imposed in the fits. Finally the new Y*’s observed in this experiment are classified inSU3 multiplets.

New Data on K- p --> omega Lambda from 1.934-GeV/c to 2.516-GeV/c and Partial Wave Analyses from Threshold Up to 2436-MeV CMS Energy

We present the results of a bubble chamber study of the pure-isospinI = 0 reaction K−p → ωΛ at 7 incident momenta between 1.934 and 2.516 GeV/c. An energy-dependent partial-wave analysis in the c.m. energy range (2070 ÷ 2436) MeV including these new data confirms the coupling of theG7 Λ(2100) to this channel and yields evidence for the existence of a new resonant stateD3or P3 Λ(2325). A semi-energy-independent partial-wave analysis is also carried out, by means of all available data from the threshold of the K−p → ωΛ reaction up to 2436 MeV. This supplies clear and unambiguous evidence for the contribution of the knownP3 Λ(1860) and of the above-proposedD3 Λ(2325) to the ωΛ channel.
