Elastic scattering of negative kaons on polarized protons between 865 and 1330 MeV/c

Coupled-channel model forK¯Nscattering in the resonant region

“…The KN → KN data constitute almost half of the experimental database. However, the amount of polarization data is small with no data below p lab = 865 MeV/c [15]. In Figs.…”

“…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 .…”

“…The momentum of the incoming K − in the laboratory frame is shown for each plot. Differential cross section data from [13-15, 18, 23, 24], polarization data from [13][14][15], and P dσ dΩ data from [14,15].…”

“…15 poles. KSU, KA, and we agree within errors on the Σ(1915) state for the F 15 partial wave and we get a similar result for Σ(2070) to the one of KSU.…”
