K−p cross sections from440 to 800 MeV/c

Partial-wave analysis ofK¯Nscattering reactions

“…Figure 2 shows the comparison of differential cross section data for K − p → K − p with our energy-dependent solution at four lab momenta of 514, 935, 1165, and 1483 MeV. Although the data are from the 1960s and 1070s [2,11,16,22] they are in excellent agreement with our solution. For (Fig.…”

“…From the table, we see that in the n = 0 shell there are two P waves: Σ(1193)P 11 and Σ(1385)P 13 . While in the n = 1 shell, there exist three S 11 waves: [ [57] (open squares), [58] ( solid circles), [70] (left-triangles), [66] (right-triangles), [71] (down-triangles), [77] (up-triangles), [63] (open circles), [67] (solid squares), [69] Our results compared with the data have been shown in Figs. 6 and 7.…”

“…Our theoretical results of Σ 0 polarizations show some agreement with the measurements from [77] at backward angles. [61] ( solid circles), [57] (solid diamonds), [60] (left-triangles), [59] (up-triangles), [76] (open squares), and [67] From the ratios, it is found that the Λ(1405)S 01 and Λ(1520)D 03 govern the contributions of S and D waves, respectively, in the reaction. The reversed signs in the two S waves (D waves) indicates that they have destructive interferences each other.…”

“…However, we also notice that our theoretical results might underestimate the differential cross sections at forward angles in the higher energy region P K − 560 MeV/c (W 1.59 GeV). [58] (diamond), [77] (solid circles), [57] (open squares), [64] (up triangles).…”
