K0(L) p Charge Exchange Scattering from 550-MeV/c to 1000-MeV/c

Edelstein, R.M. ; Fisk, H.E. ; Joseph, P. ; et al.

Phys.Rev.D 14 (1976) 702-707, 1976.

Inspire Record 115726 DOI 10.17182/hepdata.24674

Employing a neutral kaon beam at the Argonne Zero Gradient Synchrotron, a high-resolution magnetic spectrometer, and a neutron detector, differential cross sections have been obtained in the forward direction [0.045<|t|<0.18 (GeV/c)2] for the reaction KL0p→K+n. Previous studies of the time-reversed process in deuterium, K+d→K0p(p), have not yielded direct cross-section measurements in the forward direction because there is an inhibition of the non-spin-flip process in deuterium due to the Pauli exclusion principle. Nevertheless, our data are in agreement with the extracted free-neutron cross sections of deuterium studies as determined from the impulse and closure approximations.

Reaction K- p --> Lambda pi0 from 1647-MeV to 1715-MeV

Ponte, R.A. ; Hertzbach, Stanley S. ; Button-Shafer, Janice ; et al.

Phys.Rev.D 12 (1975) 2597-2609, 1975.

This paper contains the results of a study of the reaction K−p→Λπ0 in the center-of-mass-system-energy region of 1647 to 1715 MeV. An energy-dependent partial-wave analysis was performed in this channel. Two allowable solutions were obtained. The first solution in this region contains the D13[t=0.08±0.01, Γ(ER)=44±11 MeV, and ER=1671±3 MeV] partial wave as the only resonant amplitude; the second solution contains both the P11[t=0.16±0.01, Γ(ER)=81±10 MeV, and ER=1671±2 MeV] and the D13[t=0.17±0.01, Γ(ER)=76±5 MeV, and ER=1655±2 MeV] partial wave as resonant.

K-minus-p interactions from 594 to 820 mev/c

Bertanza, L. ; Bigi, A. ; Carrara, R. ; et al.

Phys.Rev. 177 (1969) 2036-2047, 1969.

Inspire Record 55654 DOI 10.17182/hepdata.70773

K−−p interactions in the Columbia-BNL 30-in. hydrogen bubble chamber were studied at nine momenta from 594 to 820 MeVc. The results for elastic-scattering and zero-prong-plus-V0 events are presented here. Differential cross sections are given for the K−p, K¯0n, and Λπ0 final states. A fit to the K¯N channels was obtained which shows the effects of a 32− resonance at 1701 MeV. This energy is appreciably displaced from the peak in the inelastic cross section.

Polarization of Recoil Protons Produced in Elastic Scattering at 307 Mev

Grigor'ev, E.L. ; Mitin, N.A. ;

Sov.Phys.JETP 10 (1960) 295-301, 1960.

Inspire Record 1096726 DOI 10.17182/hepdata.12

Results are presented of an investigation of the polarization of recoil protons appearing in elastic 1r+ -p scattering through an angle of 140 ± 8° in the c.m.s. at an energy of 307 ± 5 Mev. A polarization value P 1 = -0.19 ± 0.17 has been deriver from the data on the magnitude of the left-right asymmetry in elastic scattering of recoil protons on photographic emulsion nuclei. Phase shifts satisfying the indicated polarization value and consistent with the differential cross section for elastic scattering of 71"+ -mesons by protons are given by Eq. (1). Problems connected with the use of various phase shift sets for analysis of the experimental data are discussed.
