The Fermilab hybrid 30-in. bubble-chamber spectrometer was exposed to a tagged 147-GeV/c positive beam containing π+, K+, and p. A sample of 3003 K+p, 19410 pp, and 20745 π+p interactions is used to derive σn, 〈n〉, f2cc, and 〈nc〉D for each beam particle. These values are compared to values obtained at other, mostly lower, beam momenta. The overall dependence of 〈n〉 on Ea, the available center-of-mass energy, for these three reactions as well as π−p and pp interactions has been determined.

Topological and Leading Particle Cross-Sections for 147-GeV/c $\pi^- p$ Interactions.

Fong, D.G. ; Heller, M. ; Shapiro, A.M. ; et al.
Phys.Lett.B 53 (1974) 290-296, 1974.
Inspire Record 93415 DOI 10.17182/hepdata.27916

Results are reported based on a study of π − p interactions at 147 GeV/ c in the FERMILAB 30-inch Proportional Wire Hybrid Bubble Chamber System. We have measured the topological cross sections and separated two-prong elastic and inelastic channels. In addition, we have extracted leading particle cross sections using the increased momentum resolution of the downstream proportional wire chambers. We have compared our results with experiments and predictions of a simple fragmentation hyphothesis.

The Real Part of the Forward Proton Proton Scattering Amplitude Measured at the CERN Intersecting Storage Rings

Amaldi, U. ; Cocconi, G. ; Diddens, A.N. ; et al.
Phys.Lett.B 66 (1977) 390-394, 1977.
Inspire Record 110800 DOI 10.17182/hepdata.27584

The real part of the proton proton elastic scattering amplitude has been determined from its interference with the Coulomb amplitude at total centre-of-mass energies up to 62 GeV. The observed steady increase of ϱ with energy indicates that the total proton proton cross section continues to increase well beyond this energy.

The Energy dependence of the proton proton total cross-section for center-of-mass energies between 23 and 53 GeV

Phys.Lett.B 44 (1973) 112-118, 1973.
Inspire Record 83729 DOI 10.17182/hepdata.28110

Measurements of proton-proton elastic scattering at angles around 6 mrad have been made at centre-of-mass energies of 23, 31, 45 and 53 GeV using the CERN Intersecting Storage Rings. The absolute scale of the cross-section was established by determination of the effective density of the colliding beans in their overlap region. Proton-proton total cross sections were deduced by extrapolation of the elastic differential cross-section to the forward direction and by application of the optical theorem. The results indicate that over the energy range studied the proton-proton total cross-section increases from about 39 to about 43 mb.

Study of Elastic $\pi^+ p$, $K^+ p$ and $p p$ Scattering at 250-{GeV}/$c$

Inspire Record 246909 DOI 10.17182/hepdata.40833

Results are presented on π + p and K + p elastic scattering at 250 GeV/ c , the highest momentum so far reached for positive meson beams. The experiment (NA22) was performed with the european hybrid spectrometer. The π + p elastic cross section stays constant with energy while the K + p cross section increases.

Spin correlation measurements for p (polarized) + p (polarized) elastic scattering at 497.5-MeV

Hoffmann, G.W. ; Barlett, M.L. ; Kielhorn, W. ; et al.
Phys.Rev.C 49 (1994) 630-632, 1994.
Inspire Record 383760 DOI 10.17182/hepdata.25964

The spin correlation parameter A00NN for 497.5 MeV proton + proton elastic scattering was determined over the center-of-momentum scattering angle region 23.1°–64.9 °. The new A00NN extend to more forward angles than existing A00NN and have significantly smaller statistical errors (±0.01–0.04). The A00NN are qualitatively described by recent phase shift analyses, but a quantitative shape and normalization discrepancy remains in the forward angle region. These new data provide important constraints for nucleon-nucleon spin-dependent amplitudes at forward angles which are used in theoretical models of nucleon-nucleus scattering.

Proton-Proton Scattering at 1.48 BeV

Eisner, A.M. ; Hart, E.L. ; Louttit, R.I. ; et al.
Phys.Rev. 138 (1965) B670-B677, 1965.
Inspire Record 944962 DOI 10.17182/hepdata.461

A sample of 2657 proton-proton scattering events at 1.48 BeV has been analyzed. The elastic cross section is 19.86 mb, and the elastic scattering is consistent with a simple opaque-disk optical model with R=0.91 F and 1−a=0.864. The dominant feature of the inelastic scattering is the production of the (3/2, 3/2) isobar. The reaction p+p→p+n+π+ is interpreted satisfactorily in terms of the one-pion-exchange model.

Proton proton elastic scattering and nucleon resonance production at high-energies

Allaby, J.V. ; Diddens, A.N. ; Dobinson, R.W. ; et al.
Nucl.Phys.B 52 (1973) 316-382, 1973.
Inspire Record 73454 DOI 10.17182/hepdata.32650

Angular distributions of proton-proton elastic scattering have been measured for incident beam momenta of 10.0, 12.0, 14.2 and 24.0 GeV/ c over a range of lab scattering angles from 12 to 152 mrad. This is equivalent to a range of four-momentum transfer squared from about 0.1 to 6.7 GeV 2 at the highest momentum. Nucleon resonance production in the two-body reaction p + p → p + X has been studied at 24.0 GeV/ c incident momentum from 13.5 to 112 mrad by measuring the proton momentum spectra from the elastic peak down to a momentum corresponding to a missing mass of about 2.6 GeV. The new data are compared with previous results and theoretical models.
