Nucleon Isobar Production in Proton-Proton Collisions between 3 and 7 GeVc

Ankenbrandt, C.M. ; Clark, A.R. ; Cork, Bruce ; et al.

Phys.Rev. 170 (1968) 1223-1236, 1968.

Inspire Record 54418 DOI 10.17182/hepdata.26506

A systematic study has been made of the reactions pp→pp and pp→pN* in the angular range from θlab=10∘ to θc.m.=90∘ at 3, 4, 5, 6, and 7 GeVc. An orthogonal dispersion magnetic spectrometer detected protons from interactions in hydrogen with momentum transfer (−t) in excess of 0.5 (GeV)2. Well-defined peaks in the missing-mass spectra occurred at average N* masses of 1240±6, 1508±2, and 1683±3 MeV with average full widths of 102±4, 92±3, and 110±4 MeV, respectively. Below 2400 MeV no other significant enhancements were found. The N* production cross sections dσdt near θc.m.=90∘ are in qualitative agreement with the predictions of the statistical model. For each isobar the differential cross section at fixed energy varies as exp(−vv0), where v≡[−tu(t+u)]; v0 varies systematically with energy and tends toward the same value (≈0.4 GeV2) for each isobar at the upper limit of our energy range.

Elastic scattering and single-pion production in proton proton interactions at 6.92 bev/c

Alexander, G. ; Carmel, Z. ; Eisenberg, Y. ; et al.

Phys.Rev. 173 (1968) 1322-1329, 1968.

Inspire Record 55956 DOI 10.17182/hepdata.5540

Elastic scattering and single-pion production in pp collisions at 6.92 BeVc were studied in the BNL 80-in. hydrogen bubble chamber. Partial cross sections for the different final states are given. The reaction pp→nN1238*(pπ+) with σ=1.9±0.3 mb is analyzed and is in agreement with the modified one-pion-exchange model. Single-pion production can be explained as due mainly to two channels: (a) pp→N1238*(pπ+)n, and (b) pp→p(nπ+) or pp→p(pπ0), where the (nπ+) and (pπ0) pairs are in an I=12 state.

Two-prong events in proton proton interactions at 8.1 gev/c

Ginestet, J. ; Manesse, D. ; Tran, Ha Anh ; et al.

Nucl.Phys.B 13 (1969) 283-293, 1969.

Inspire Record 56040 DOI 10.17182/hepdata.8347

About 10 000 two-prong events of 8.1 GeV/ c proton-proton interactions in the CERN 2 m. bubble chamber have been analyzed. We study elastic scattering and single-pion production reactions. We give cross sections for isobar production. We attempt to interpret the general features of the pp→pn π + reaction by the Deck mechanism. We compare the production and the decay of δ ++ (1236) with absorption or π Regge trajectory exchange models.

Energy dependence of the structure in high energy proton proton elastic scattering

Allaby, J.V. ; Diddens, A.N. ; Robinson, R.W. ; et al.

Phys.Lett.B 34 (1971) 431-434, 1971.

Inspire Record 69311 DOI 10.17182/hepdata.28522

The angular distribution of proton-proton elastic scattering has been measured for incident beam momenta of 10.0, 12.0, 14.2 and 24.0 GeV/ c over a range of laboratory scattering angles from 12 to about 140 mrad. The results are compared with the fourth power of the electromagnetic form of the proton.

Proton proton differential cross-sections from 600 to 1800 mev/c

Ryan, B.A. ; Kanofsky, A. ; Devlin, T.J. ; et al.

Phys.Rev.D 3 (1971) 1-9, 1971.

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.
