SINGLE pi+- AND K+ PHOTOPRODUCTION FROM COMPLEX NUCLEI AT 8-GeV AND 16-GeV

Boyarski, A. ; Diebold, Robert E. ; Ecklund, Stanley D. ; et al.
Phys.Rev.Lett. 23 (1969) 1343-1346, 1969.
Inspire Record 54879 DOI 10.17182/hepdata.21641

The reactions γA→π±A* have been studied at four-momentum transfers −t<~0.5 GeV2 for seven elements ranging from hydrogen to lead. Exclusion-principle suppression is clearly visible at small-momentum transfer. Neither the A dependence nor the energy dependence of the cross sections agrees with the predictions of the vector-dominance model. The ratio of π−π+ production requires equal spatial distributions for the protons and neutrons in nuclei. Some K+ data are also presented.

Gamma p INTERACTIONS AT 5.25-GeV

Ballam, Joseph ; Chadwick, G.B. ; Guiragossian, Zaven G.T. ; et al.
Phys.Lett.B 30 (1969) 421-425, 1969.
Inspire Record 54868 DOI 10.17182/hepdata.28894

Photoproduction of resonances has been studied using positron annihilation radiation at 5.25 GeV in the SLAC 40-inch hydrogen bubble chamber. Results are presented on the nonstrange particle events and related to the vector dominance model.

Photoproduction of negative pions on neutrons at photon energies between 0.2-GeV and 2.0-GeV

The Aachen-Berlin-Bonn-Hamburg-Heidelberg-Muenchen collaboration Hilpert, H.G. ; Lauscher, P. ; Matziolis, M. ; et al.
Nucl.Phys.B 8 (1968) 535-544, 1968.
Inspire Record 56298 DOI 10.17182/hepdata.32389

Total and differenial cross sections of the reaction γ +n→p+ π − have been determined for photon-energies between 0.2 and 2.0 GGeV. Below 500 MeV the differential cross sections are compared with theoretical predictions derived from fixed-momentum-transfer dispersion relations.

Differential cross-sections for the reactions $p + p \to D + \pi^+$ and $p + p \to D + \rho^+$ at 21-GeV/c

Allaby, J.V. ; Binon, F.G. ; Diddens, A.N. ; et al.
Phys.Lett.B 29 (1969) 198-202, 1969.
Inspire Record 56770 DOI 10.17182/hepdata.28992

Results are presented from an experiment in which high-energy deuterons, produced by proton-proton interactions at 21.1 GeV/ c incident momentum, were detected over a range of angles from 12.5 mrad to 60 mrad in the laboratory system. From the momentum spectra of the deuterons, the final states D + π + and D + ϱ + have been identified. The angular distribution for these reactions are presented and compared with previous data at lower energies.

A study of the reaction pi-minus + p ---> lambda + anti-lambda + n at 7 and 12 gev/c

Beusch, W. ; Fischer, W.E. ; Pepin, M. ; et al.
Phys.Lett.B 28 (1968) 211-214, 1968.
Inspire Record 56830 DOI 10.17182/hepdata.29078

Over 100 unambiguous π − + p → Λ + Λ + n events have been observed in a magnet spark chamber. The data provide good evidence for peripheral production of Λ Λ and n Λ (via meson exchange) and against peripheral n Λ (double baryon exchange). No resonances in the Λ Λ system are observed. Angular distributions and Λ( Λ ) polarizations are analysed.
