Inspire Record 261496 DOI 10.17182/hepdata.20075

Cross sections for 180° inelastic electron scattering from deuterium were measured from breakup threshold to beyond the quasielastic peak for incident-beam energies of 0.843, 1.020, 1.189, and 1.281 GeV, corresponding to 0.75≤Q2≤2.57 (GeV/c)2. The data are in reasonable agreement with nonrelativistic models that include final-state interactions and meson-exchange currents. The scaling function F(y) for these data is generally in agreement with F(y) for forward-angle data at the same Q2. Values of GMn determined from the data are in good agreement with results from previous experiments.

MEASUREMENT OF THE REAL TO IMAGINARY RATIO OF THE ANTI-P P FORWARD SCATTERING AMPLITUDES

Ashford, V. ; Sainio, M.E. ; Sakitt, M. ; et al.
Phys.Rev.Lett. 54 (1985) 518-521, 1985.
Inspire Record 216074 DOI 10.17182/hepdata.20329

We have measured the ratio of the real to the imaginary parts of the p¯p forward-scattering amplitude in the incident-momentum range 360 to 650 MeV/c. These results are in good agreement with predictions of the Paris nucleon-antinucleon potential model which include spin-flip effects.

NEUTRAL PION PHOTOPRODUCTION AND PROTON COMPTON SCATTERING AT LARGE ANGLES

Shupe, M.A. ; Milburn, Richard H. ; Quinn, D.J. ; et al.
Phys.Rev.D 19 (1979) 1921-1930, 1979.
Inspire Record 145744 DOI 10.17182/hepdata.24315

The differential cross sections for γp→γp and γp→π0p have been measured for incident photon energies in the range of 2 to 6 GeV and for |t| ranging from 0.7 to 4.3 GeV2. This corresponds to a center-of-mass angle range of 45° to 128°. The energy dependence of the data is compared to that predicted by several parton models.

LOW-ENERGY ANTI-PROTON NUCLEAR ABSORPTION CROSS-SECTIONS

Ashford, V. ; Sainio, M.E. ; Sakitt, M. ; et al.
Phys.Rev.C 31 (1985) 663-665, 1985.
Inspire Record 215612 DOI 10.17182/hepdata.50305

We have studied the absorption cross section of antiprotons on Al, Cu, and Pb for T=131.6 and 193.6 MeV. These results are compared with predictions of an optical model fitted to antiproton elastic scattering data on these nuclei and are in agreement with these predictions. The cross sections have an exponential dependence on the mass number A with an exponent of approximately 0.61.

A Luminosity Independent Measurement of the $\bar{p} p$ Total Cross-section at $\sqrt{s}=1$.8-tev

Phys.Lett.B 243 (1990) 158-164, 1990.
Inspire Record 27474 DOI 10.17182/hepdata.29696

We report a measurement of the p p total cross section at √ s =1.8 TeV using a luminosity-independent method. Our result is σ T =72.1±3.3 mb ; we also derive the total elastic cross section σ el =16.6±1.6 mb. A value is obtained for the total single diffraction cross section of 11.7±2.3 mb.

Measurement of the Total and Partial anti-p p Cross-Section Between 1901-MeV and 1950-MeV

The CERN-Liverpool-Mons-Padua-Rome-Trieste collaboration Chaloupka, V. ; Drevermann, H. ; Marzano, F. ; et al.
Phys.Lett.B 61 (1976) 487-492, 1976.
Inspire Record 108895 DOI 10.17182/hepdata.27669

The presence of a structure in the p̄p total cross section at 1930–1940 MeV, with a narrow width of 9 MeV is confirmed. The interpretation of the effect as a single, non interfering, resonance is made difficult by the comparison of the elastic scattering with the charge exchange cross sections.

SEARCH FOR THE S MESON IN ANTI-PROTON PROTON INTERACTIONS

Inspire Record 239036 DOI 10.17182/hepdata.26472

The interaction between antiprotons and protons has been studied in the range 1910 to 1990 MeV center-of-mass energy in a drift-chamber experiment at the Brookhaven Alternating Gradient Synchrotron. The total cross section has been determined at eleven different incident momenta, and the elastic cross section between 8 and 30 deg in the laboratory has been measured with an energy resolution of about 5 MeV. The cross section for annihilation into charged mesons has also been measured, with the same resolution. There is no evidence in any of these channels for the existence of a narrow resonance.

Inspire Record 281851 DOI 10.17182/hepdata.19995

We have measured the antiproton-proton total cross section at √s =1.8 TeV at the Fermilab Tevatron Collider; the value obtained is 78.3±5.9 mb. B, the nuclear slope parameter for elastic scattering, was measured to be 16.3±0.5 (GeV/c)−2. From these data, we derive a value for the total elastic cross section.
