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 pi0 WITH PLANE POLARIZED 3-Gev PHOTONS

Bellenger, D. ; Bordelon, R. ; Cohen, K. ; et al.
Phys.Rev.Lett. 23 (1969) 540, 1969.
Inspire Record 55099 DOI 10.17182/hepdata.21666

The cross section for photoproduction of π0 mesons was measured at a photon energy of 3 GeV and squared four-momentum transfer (t) of -0.1 to -1.2 (GeV/c)2 using plane-polarized photons. The asymmetry was found to be consistent with +1.0 for t values above -0.4 and below -1.1. For −0.4<~t<~−1.0 there is a dip in the asymmetry and at t=−0.6 it drops to 0.55 ± 0.15. This result precludes a simple Regge model with ω0 and B; a theoretical description requires Regge cuts or an ω′ exchange.

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.

Production of xi- and antixi+ particles in k+ p collisions at 12.7 gev/c

Stone, S.L. ; Berlinghieri, J.C. ; Bromberg, C. ; et al.
Phys.Lett.B 32 (1970) 515-518, 1970.
Inspire Record 63098 DOI 10.17182/hepdata.28710

The cross section for the production of Ξ + particles in K + p interactions at 12.7 GeV/ c is 10 ± 3 μ b; the Ξ − production cross section is 2.5 ± 1.0 μ b; the upper limit on Ω − or Ω + production is 0.4 μb. The Ξ − are produced preferentially in the backward direction in the CM system while the Ξ + are produced mainly forward. The mass and lifetime of the Ξ + agree with the accepted values for the Ξ − hyperon.

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.
