A simultaneous partial-wave analysis of the three final states K + p, K ∗ (892)N and KΔ(1236) is attempted using inelastic data with large statistics at 1.21, 1.29, 1.38 and 1.69 GeV/ c as well as existing data on the elastic reaction. The constraint of unitarity, which is almost saturated by these reactions, allows one to determine the size and relative phases of the dominant partial waves and to give some limits on the others. Their variation with energy is discussed, as well as the consistency of the different sets of elastic phase shifts with the inelastic data. We also compare the predictions of the duality hypothesis with the data.

Elastic scattering and single-pion production in k+ p reactions at 4.27 gev/c

Seidl, A. ;
Phys.Rev.D 7 (1973) 621-636, 1973.
Inspire Record 82569 DOI 10.17182/hepdata.22113

Elastic K+p scattering at a beam momentum of 4.27 GeV/c is studied and compared with elastic K−p scattering in order to extract the imaginary part of the non-Pomeranchukon-exchange amplitude. The single-pion-production cross sections are presented as well as production cross sections and resonance parameters for the Δ(1236), the K*+(890), and the K*+(1420). Production and decay distributions for the Δ++(1236) and the K*+(890) are presented and compared with the absorptive particle-exchange model and with Regge-pole-exchange models.

Inspire Record 1720 DOI 10.17182/hepdata.1112

Baryon resonance production in quasi-two-body reactions has been studied for the channels K + p→K°p π + , K + n π + and K + p π ° at beam momenta of 2.53, 2.76 and 3.20 GeV/ c . The production cross sections, four-momentum transfer distributions and density matrix elements are given for the Δ(1236), N ∗ (1400), N ∗ (1500) and N ∗ (1680) states. The reaction K + p→K° Δ ++ (1236) is compared to the line reversed reaction K − n → K °Δ − and the charge-exchange SU(3) sum rule for pseudo-scalar meson plus Δ(1236) is tested.
