Photoproduction cross sections for $\pi^+$ and $K^+$ mesons at 3.4 to 4.0 {GeV} and their comparison with {SU(3)}

Elings, V.B. ; Cohen, K.J. ; Garelick, D.A. ; et al.
Phys.Rev. 156 (1967) 1433-1443, 1967.
Inspire Record 51624 DOI 10.17182/hepdata.406

The differential cross sections for the photoproduction reactions γ+p→π++n, γ+p→K++Λ0, and γ+p→K++Σ0 have ben measured for incident laboratory photon energies between 3.4 and 4.0 GeV and for meson center-of-mass angles from about 25° to 45°. The reactions were studied by observing only the charged mesons. The momenta, velocities, and angles of the mesons were measured with a magnetic spectrometer, and the equivalent of nearly monochromatic gamma rays was obtained by performing bremsstrahlung subtractions. The cross sections agree with the inequality predicted from unbroken SU(3). The measured behavior of dσdt as a function of t shows similarities to that observed in studies of mesonnucleon scattering.

Photoproduction of neutral rho mesons from complex nuclei

Alvensleben, H. ; Becker, U. ; Bertram, W.K. ; et al.
Phys.Rev.Lett. 24 (1970) 786-792, 1970.
Inspire Record 62918 DOI 10.17182/hepdata.21623

We present results of measurements on photoproduction of ρ mesons. Analysis of 106 measured ρ events in a four-dimensional data matrix dσ(A, m, p, t⊥)dΩdm with dimensions 14×20×10×20 yields precise information on nuclear density distributions for ρ production. We obtain for the Woods-Saxon radii R(A)=(1.12±0.02)A13 and, using the vector dominance model, σρN=26.7±2.0 mb and γρ24π=0.57±0.10.

Determination of the photoproduction phase of rho0 mesons

Inspire Record 68820 DOI 10.17182/hepdata.33835

We have measured large-angle electron-positron pairs from the reaction γ +Be → Be+e + +e − in the e + e − invariant-mass region of 610 < m < 850 MeV/ c 2 . The phase of the photoproduction amplitude of the ϱ-meson at 4.1 – 6.1 GeV was found to deviate from pure imaginary by 11.8° ± 4.4° which corresponds to a ratio of the real to imaginary ϱ-nucleon amplitude of β = −0.2 ± 0.1.

Total cross-sections for pi- p ---> lambda k0 from threshold to 1.13 gev/c

Jones, J.J. ; Bowen, T. ; Dawes, W.R. ; et al.
Phys.Rev.Lett. 26 (1971) 860-863, 1971.
Inspire Record 69027 DOI 10.17182/hepdata.21505

Total cross sections for π−p→ΛK0 have been measured using optical spark chambers from threshold to 1.13−GeVc beam momentum in 19−MeVc intervals, but with a 1−MeVc resolution in the regions of the ΛK and ΣK thresholds. The behavior near ΛK threshold indicates a significant s-wave contribution, but this experiment is unable to resolve any cusplike behavior in the region of the ΣK thresholds. The cross section shows a broad peak in the vicinity of 1.05−GeVc beam momentum.

K0(s) k- decay of a2- produced by 20.3-gev/c pi- on hydrogen

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.
Phys.Rev.D 6 (1972) 747-756, 1972.
Inspire Record 73969 DOI 10.17182/hepdata.22252

We present the results of an analysis of data for the reaction π−p→KS0K−p at 20.3-GeV/c incident π momentum. We find that the K0K− effective-mass spectrum shows a single peak in the A2 region which is well fitted by a Breit-Wigner shape. The data in the A2-peak region are inconsistent with the split-A2 shape reported earlier. The distribution in t of the A2 events shows a forward dip followed by an exponential falloff. The A2 decay angular distribution is well fitted by a single resonance with quantum numbers JP=2+. The results of an analysis of the density-matrix elements for this reaction are given.
