$\bar{p} -p$ Elastic Scattering at 6.9 GeV/c

Kitagaki, T. ; Takahashi, K. ; Tanaka, S. ; et al.

Phys.Rev.Lett. 21 (1968) 175-177, 1968.

Inspire Record 54434 DOI 10.17182/hepdata.198

The p¯−p elastic scattering at 6.9 GeV/c was studied by the analysis of antiproton film taken by the Brookhaven National Laboratory 80-in. hydrogen bubble chamber. The cross section of the elastic scattering was 14.7 ± 1.5 mb. The angular distribution showed a dip in the region of −t≈0.6 (GeV/c)2 and a secondary maximum at −t≈0.8 (GeV/c)2.

PHOTOPRODUCTION OF eta0 MESONS AT 4-Gev

Bellenger, D. ; Deutsch, S. ; Luckey, David ; et al.

Phys.Rev.Lett. 21 (1968) 1205, 1968.

Inspire Record 53018 DOI 10.17182/hepdata.21703

We have measured η0 photoproduction at 4 GeV. We find our results to be consistent with a theoretical preduction relating this cross section to ω0 production by π mesons using a vector-dominance model; there is no evidence for a dip or change of slope at −t=0.6 as seen in π0 photoproduction.

MEASUREMENTS OF PI0 PHOTOPRODUCTION CROSS-SECTIONS FOR INCIDENT GAMMA-RAY ENERGIES OF 2.0-Gev/c TO 5.0-Gev/c

Phys.Rev.Lett. 18 (1967) 926, 1967.

Inspire Record 51286 DOI 10.17182/hepdata.21770

Cross sections for the reaction γ+p→π0+p for incident gamma-ray energies of 2.0 to 5.0 GeV and for baryon four-momentum transfers squared of 0.5 to 4.0 (GeV/c)2 are presented. The results are compared with theoretical predictions based on Reggeized vector-meson exchange.

Electrodisintegration of the Deuteron Around q2=3.5 F-2

Grossetete, B. ; Jullian, S. ; Lehmann, P. ;

Phys.Rev. 141 (1966) 1435-1440, 1966.

Inspire Record 944958 DOI 10.17182/hepdata.462

We have measured the absolute cross sections of the electron-deuteron scattering at q2=3.5 F−2 and obtained the complete inelastic spectrum. Three points for each spectrum are given with a 4% accuracy. The scattering angles, 60° and 130°, were chosen to allow the separation between electric and magnetic scattering. Calculations of radiative corrections were made in order to permit the comparison of the spectra with the inelastic-scattering theories.

pi+ proton, pi- proton and pp elastic scattering at 8.5, 12.4 and 18.4 GeV/c

Harting, D. ; Blackall, P. ; Elsner, B. ; et al.

Nuovo Cim. 38 (1965) 60, 1965.

Inspire Record 49759 DOI 10.17182/hepdata.1110

Approximately 60 000 events have been collected in a spark chamber experiment at the CERN Proton Synchrotron which studied elastic diffraction scattering of π--p and p-p at incident momenta of 8.5, 12.4 and 18.4 GeV/c and of π+-p at 8.5 and 12.4 GeV/c. Magnetic analysis of the incoming and diffraction scattered particle, together with measurement of all angles, permitted each event to be determined as elastic subject to three constraints, so that the inelastic background was rejected with. high efficiency, even at the larger momentum, transfers. Much of the data have been processed by the CERN Automatic Flying-Spot DigitizerHPD. A detailed description of the experimental technique and of the methods of analysis is given. The results, together with data from lower energies, confirm the remarkable energy-independence of the shape of the pion-proton diffraction scattering peak up to |t| = 1.5 (GeV/c)2, wheret is the square of the four-momentum transfer, over a range of pion energies from 2 to 18 GeV. Proton-proton scattering does however appear to show a shrinking diffraction peak. In general, the data agree with other experiments using both counter and bubble chamber techniques, but some differences do appear. During the experiment, data were taken which set an upper limit of 2·102 μb/(GeV/c)2 on the differential elastic cross-section dσ/dt over a range of |t| from 20.9 to 23.4 (GeV/c)2 at 13.4 GeV/c incident pion momentum.
