Bugg, D.V. ; Edgington, J.A. ; Amsler, Claude ; et al.
J.Phys.G 4 (1978) 1025, 1978.
Inspire Record 123232 DOI 10.17182/hepdata.38563

The parameters D, R, R' and P for pp elastic scattering have been measured in the centre-of-mass angular range 13 degrees to 58 degrees with an accuracy of about +or-0.02 at 209, 324, 379, 425 and 515 MeV. These results are incorporated with earlier data into a phase-shift analysis. Phase-shifts are generally in agreement with the theoretical predictions of the Paris group, although the F-wave spin-orbit combination is rather stronger than predicted. The fitted value for the pi 0pp coupling constant in g02=14.06+or-0.65.

The Differential Cross-section for Proton Proton Elastic Scattering at 90-degrees $c$.m. Between 300-{MeV} and 500-{MeV}

Ottewell, D. ; Walden, P. ; Auld, E.G. ; et al.
Nucl.Phys.A 412 (1984) 189-194, 1984.
Inspire Record 191877 DOI 10.17182/hepdata.37041

The absolute differential cross section for proton-proton elastic scattering has been measured at 90° c.m. for 300, 350, 400, 450 and 500 MeV. The statistical uncertainty of the measurements is 0.5% with an additional systematic normalization uncertainty of 1.8%. The results are compared to phase-shift analyses.

Measurement of the $p p$ Cross-sections in the Momentum Range 0.9-2.0 GeV/c

Shimizu, F. ; Kubota, Y. ; Koiso, H. ; et al.
Nucl.Phys.A 386 (1982) 571-588, 1982.
Inspire Record 11839 DOI 10.17182/hepdata.37042

The pp total, elastic, and all the inelastic cross sections were measured at 11 momenta in the range 0.9–2.0 GeV/c. No clear structure was observed in their momentum dependences. The momentum dependence of the total cross section agrees quite well with the result of a phase-shift analysis by Arndt. Our measurement of the ppπ 0 and pnπ + cross sections served to normalize the earlier systematic but relative and extrapolated measurements of these cross sections over a narrower momentum range. Calculations by König and Kroll based on a pion exchange model including the effect of an I = 1 dibaryon did not fit the single-pion production cross sections.

MEASUREMENT OF DELTA SIGMA-l AND C (L, L) = (L, L : 0, 0) N PROTON PROTON SCATTERING BETWEEN 300-MEV AND 800-MEV

Auer, I.P. ; Ditzler, W.R. ; Hill, D. ; et al.
Phys.Rev.D 29 (1984) 2435-2468, 1984.
Inspire Record 205458 DOI 10.17182/hepdata.23728

Measurements are reported of the difference ΔσL between proton-proton total cross sections for parallel and antiparallel spin states and of the parameter CLL for proton-proton elastic scattering near 90°, for thirteen energies between 300 and 800 MeV. The ΔσL results agree well with previous ANL ZGS and SIN data, but disagree with recent results from TRIUMF. Attempts to understand the cause of the discrepancy have been unsuccessful, but possible sources are discussed. The ΔσL and CLL results have been used with other experimental data to extract quantities which depend only on spin-singlet, coupled spin-triplet, and spin-triplet partial waves. Structure is found in these quantities, which appears to be associated with the resonantlike D21 and F33 partial waves. Additional similar structure is also found, which may be due either to the P03 partial wave or the (P23,F23) partial-wave pair.

C(LL) = (L, L: 0, 0) MEASUREMENTS AND A STRUCTURE DUE TO A P PARTIAL WAVE IN THE P P SYSTEM

Burleson, G.r. ; Cottingame, W.b. ; Greene, S.j. ; et al.
Nucl.Phys.B 213 (1983) 365-370, 1983.
Inspire Record 191085 DOI 10.17182/hepdata.34015

Measurements of C LL of pp elastic scattering near θ c.m. = 90° at thirteen energies between 300 and 800 MeV are reported. These, together with previous values of C NN , are used to extract values of two quantities, ƒ s and ƒ t , which contain only spin-singlet and only coupled spin-triplet partial waves, respectively. The ƒ s curve, which is not dependent on C LL , exhibits the behavior expected for the previously conjectured 1 D 2 resonance. The ƒ t curve also exhibits a resonance-like behavior, which could be due either to the 3 P 0 or the 3 P 2 partial wave.

Inspire Record 68275 DOI 10.17182/hepdata.23725

Proton-proton elastic differential cross sections have been measured for incident laboratory momenta of 600-1800 MeVc and c.m. angles of 5°-90°. The data span, in a single experiment, the intermediate energy region from isotropic differential cross sections at lower energies to the development of a clear diffraction peak at higher energies. Parameters for phenomenological formulations derived from the experimental results are presented.

Wide Angle Differential Cross-Sections for Elastic Proton Proton Scattering in the Region of Delta (1236) Production

Phys.Rev.D 12 (1975) 1-5, 1975.
Inspire Record 103521 DOI 10.17182/hepdata.24866

Differential cross sections for p−p elastic scattering are presented with scattering angles in the center-of-mass system greater than 35° to 50°. The data were obtained at incident laboratory momenta 0.857, 1.091, 1.210, 1.374, 1.405, and 1.501 GeV/c. This spans the region of the onset of Δ(1236) production and where a possible spin-singlet D-wave resonance is indicated in an analysis of earlier data.
