K+-Meson Production in p-p Collisions at 2.5-3.0 GeV

Hogan, W.J. ; Piroue, P.A. ; Smith, A.J.S. ;

Phys.Rev. 166 (1968) 1472-1481, 1968.

Inspire Record 54415 DOI 10.17182/hepdata.26524

Differential cross sections as a function of momentum are presented for the production of K+ mesons in p−p collisions at incident proton energies of 2.54, 2.88, and 3.03 GeV. The measurements were made at 20°, 30°, and 40° relative to the direction of the internal proton beam of the Princeton-Pennsylvania accelerator. At 2.54 GeV, the results follow closely the predictions from phase space (with 60% K+ΣN and 40% K+Λp in the final state). At 2.88 and 3.03 GeV, however, there is a definite disagreement with phase space. The data are compared to the predictions of three models: (1) a model based on the assumption that K's are produced via p+p→K++X+, where X+ is a B=2, S=−1 resonance which decays into a nucleon+hyperon; (2) the isobar model; and (3) the one-pion-exchange model. Model (1) is found to be inconclusive, model (2) is inadequate, and model (3) is partly successful in predicting total cross sections, but not in interpreting the detailed experimental observations.

Negative Hyperon Production in High-Energy Proton Interactions

Hungerbuhler, V. ; Majka, R. ; Marx, J.N. ; et al.

Phys.Rev.D 12 (1975) 1203-1210, 1975.

Inspire Record 104138 DOI 10.17182/hepdata.4668

Momentum spectra for forward Σ− and Ξ− production by protons on beryllium are presented. Σ− production data for two primary proton momenta are compared to test scaling of the invariant cross section. In addition, the observed single-particle momentum distributions are compared with single-particle spectra from other inclusive reactions initiated by protons.

Measurement of the Inclusive Forward Neutron Spectrum Produced in Proton-Copper Interactions at 24-GeV/c

Ansorge, R.E. ; Carter, J.R. ; Mount, R.P. ; et al.

Nucl.Phys.B 97 (1975) 439-444, 1975.

Inspire Record 103793 DOI 10.17182/hepdata.31931

We present data on the inclusive neutron spectra produced in the forward direction by the interactions of 23.85 GeV/ c protons in a copper target. The results are in good agreement with the predictions of the triple-Regge model.
