We have performed a partial wave analysis of the KK{sub S}°?− system produced in the reaction?−p → K+{bar K}°?−n at 8 GeV/c. We present the results of the analysis of 30,740 events in the mass range 1.24--1.60 GeV/c2, with 0.0 ≤ -t

Preliminary results are presented from the first large-statistics partial wave analysis of K−? system produced in the reaction K{sup -p {yields} K−??−?°p at 11 GeV/c observed with the LASS spectrometer at SLAC. The analysis is based on the moments of the joint angular distributions of the decay to the K−?} system, with subsequent? decay to?+?−?0. The resulting J{sup P} = 2−, 2+ and 3− amplitudes exhibit resonant behavior, and are discussed in the context of the relevant Briet-Wigner fits.

We present the results of an amplitude analysis of the spin parity components as a function of mass of the (K{bar K}°[pi]−) system as produced in the reaction {bar p}p 2!(K{bar K}°[pi]−) X. Two peaks are observed in the (K−{bar K}°[pi]−) spectrum, one at (1279 {plus minus} 2) MeV/c2 with a width of (21 {plus minus} 2) MeV/c2, and one at (1417 {plus minus} 3) MeV/c2 with a width of (62 {plus minus} 5) MeV/c2. The amplitude analysis was performed in sixteen 20 MeV/c2 mass intervals from 1.24 to 1.56 GeV/c2. The waves used for the fitting were J{sup PG} = 0{sup -+}, 1{sup ++}, 1{sup +-}, and background. 12 refs., 8 figs.
