KAON SCATTERING AND CHARGED SIGMA HYPERON PRODUCTION IN K- P INTERACTIONS BELOW 300-MEV/C

Ciborowski, J. ; Gwizdz, J. ; Kielczewska, D. ; et al.
J.Phys.G 8 (1982) 13-32, 1982.
Inspire Record 179889 DOI 10.17182/hepdata.38531

In an experiment on K--proton interactions in a hydrogen bubble chamber, the cross sections and angular distributions have been studied for elastic and charge-exchange scattering, and charged sigma hyperon production in the momentum range 90-300 MeV/c. Good agreement is found with previous cross sections except for the charge-exchange channel where the new values are 60% larger. The production distributions of the charged sigma hyperons and the polarisation of the Sigma + hyperon clearly indicate that P waves are present down to about 150 MeV/c, much lower than previously reported.

de Bellefon, A. ; Berthon, A. ; Rangan, L.K. ; et al.

We present the results on total channel cross-sections obtained in the Saclay 180 l HBC exposed to a separated K− beam at Nimrod. The cross-sections for each channel are given at 13 incident K− momenta between 1.26 and 1.84 GeV/c.

pi--p Interactions at 604 MeV

Vittitoe, C.N. ; Riley, B.R. ; Fickinger, W.J. ; et al.
Phys.Rev. 135 (1964) B232-B240, 1964.
Inspire Record 46855 DOI 10.17182/hepdata.594

The interactions of 604 MeV π− mesons in a hydrogen bubble chamber have been systematically analyzed. In 33 000 pictures a total of 8052 usable events were found, corresponding to cross sections of 18.9±1.3 mb for σ(elastic), 4.98±0.54 mb for σ(π−pπ0), 7.87±0.91 mb for σ(π−nπ+), 14.0±1.0 mb for σ(neutrals), with σ(two−pionproduction)<0.2 mb, for a total cross section of 45.9±1.9 mb at this energy. The angular distribution for elastic scattering was fitted with a fifth-order polynomial in cosθ which gave a value of dσdΩ(0°) consistent with dispersion theory. The pion-pion effective-mass distributions for both single-pion-production channels showed pronounced peaking at high mass values, strongly inconsistent with simple isobar-production kinematics. Simple one-pion exchange does not appear to play a significant role.

K+ p and k+ d total cross-sections in the momentum range 0.57-1.16 gev/c

Bowen, T. ; Jenkins, E.W. ; Kalbach, R.M. ; et al.
Phys.Rev.D 7 (1973) 22-26, 1973.
Inspire Record 82624 DOI 10.17182/hepdata.22144

K+p and K+d total cross sections were measured in the momentum range 0.57-1.16 GeV/c using a secondary, separated kaon beam of the Lawrence Berkeley Laboratory Bevatron and conventional transmission-counter techniques. No evidence was found for structure in the cross section of either reaction as previously indicated near 0.7 GeV/c.

Differential Cross-Sections for K- p Elastic Scattering from 1.4-GeV/c to 1.9-GeV/c

Abe, K. ; Barnett, B.A. ; Goldman, J.H. ; et al.
Phys.Rev.D 12 (1975) 6-14, 1975.
Inspire Record 103522 DOI 10.17182/hepdata.24826

We report here the results from an experiment to obtain differential cross sections for K−p elastic scattering in the laboratory momentum region from 1.4 to 1.9 GeV/c. These data span the region of a bump in the K−p total cross section at an energy of 2.05 GeV. Approximately 20000 elastic events were obtained at each of four momenta with an angular coverage of 0.9≥cosθc.m.≥−0.9. The data are intended to aid in phase-shift analyses of the resonances causing the bump in the total cross section and to study dip structures at constant values of the Mandelstam variables t and u.

Measurements of K − p elastic scattering have been carried out at 14 momenta between 610 MeV/ c and 943 MeV/ c over the angular range −0.9 < cos θ < 0.9. The results agree well with the best existing data and have significantly smaller errors.

$\pi^{-}+ p$ elastic scattering at 1 200 MeV

Bertanza, L. ; Carrara, R. ; Drago, A. ; et al.
Nuovo Cim. 19 (1961) 467-481, 1961.
Inspire Record 1184999 DOI 10.17182/hepdata.1109

A bubble chamber investigation of π−+p elastic scattering at 1 200 MeV (K.E.) is reported. The total and differential cross-sections are determined. By extrapolation of the angular distribution, the 0° cross-section is derived and compared with the results obtained with the help of the dispersion relations and the optical theorem. The forward peak is investigated in terms of diffraction scattering and a value for the optical radius is derived.

Elastic $\pi^{+}p$ scattering at 1.6 GeV/c

Daudin, A. ; Jabiol, M.A. ; Kochowski, C. ; et al.
Nuovo Cim. 33 (1964) 1300-1308, 1964.
Inspire Record 1187695 DOI 10.17182/hepdata.1107

The c.m. angular distribution of π+p elastic scattering at 1.6 GeV/c shows a strong forward diffraction peak decreasing exponentially with a slopeA + = (6.9±0.5) GeV−2 comparable to thatA − = (7.2±0.5) GeV−2 observed in a previous experiment for π-p elastic scattering at the same incident momentum. The behaviour of the π+ and the π− angular distributions is quite different beyond the diffraction peak. The π+p total elastic cross-section is found to be Σ01 = (16.70±0.45) mb.

Phys.Rev.D 4 (1971) 676-683, 1971.
Inspire Record 67772 DOI 10.17182/hepdata.3686

Total and differential elastic cross-section data are presented at eight incident π+ momenta: 1.28, 1.34, 1.40, 1.43, 1.55, 1.68, 1.77, and 1.84 GeVc. These data were obtained from a hydrogen-bubble-chamber exposure at the Bevatron, and contain more than 65 000 events. This represents more than 1½ times the world's data hitherto available in this energy region.
