Hyperon I: Partial-wave amplitudes for K-p scattering

“…of two existing data sets [23,24]. When both data sets were excluded from the analysis, the predicted polarization was close to the values from [23] and disagreed with [24]. Hence we decided not to use the latter data.…”

“…We chose solutions with an additional resonance and a local minimum as shown in Figs. 24. From the spread of results we estimated the errors given to masses, widths and other properties (see [30]).…”

“…Several reactions were studied at eight incident K − momenta between 514 and 750 MeV. Differential and total cross sections and the hyperon polarization were reported for the reaction K − p → ηΛ [22] and K − p → π 0 Λ, K − p → π 0 Σ, and K − p →K 0 n [23] (see also [24]), K − p → π 0 π 0 Λ [25], K − p → π 0 π 0 Σ [26]. A new path to hyperon spectroscopy was opened in Refs.…”

Coupled-channel model forK¯Nscattering in the resonant region

“…The experimental database in the resonance region with 2.19 < s < 4.70 GeV 2 , which corresponds to kaon lab momentum of 0.288 < p lab < 1.820 GeV/c, [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] contains approximately 8000 data points for theKN → KN channel (K − p → K − p and K − p →K 0 n), 4500 for theKN → πΛ channel (K − p → π 0 Λ), and 5000 for thē KN → πΣ channel (K − p → π 0 Σ 0 , K − p → π − Σ + , and K − p → π + Σ − ). This data set was analyzed in [33] and single-energy partial waves were obtained for ( I 2J ) up to J = 7/2, namely S 01 , P 01 , P 03 , D 03 , D 05 , F 05 , F 07 , G 07 , S 11 , P 11 , P 13 , D 13 , D 15 , F 15 , F 17 , and G 17 .…”
