Anti-p-p elastic scattering at 8 and 16 gev/c

Angular distributions are presented for p¯−p elastic scattering at 8 and 16 GeV/c for |t|<1.3 (GeV/c)2. At both energies there is structure in the differential cross sections in the region 0.5<~|t|<~1.0 (GeV/c)2, similar to that observed at lower energies. The diffraction peak continues to expand with increasing incident momentum.

Anti-p-p backward elastic scattering from 0.7 to 2.16 gev/c

Yoh, J.K. ; Barish, B.C. ; Nicholson, H. ; et al.

Elastic scattering of p¯ on p has been studied for cosθc.m. between -0.88 and -1.0 and Plab(p¯) between 0.70 and 2.16 GeV/c. The momentum dependence of the cross section shows a sharp dip at 0.9 GeV/c and a broad peaking around 1.4 GeV/c. The possibility of the peak resulting from direct formation of boson resonances has been studied. Alternatively, a diffraction model agrees qualitatively with our data and other elastic data at different angles.

Search for Resonance Formation in Antiproton-Proton Elastic Scattering from 1.6 to 2.2 GeV/c

We have measured the antiproton-proton elastic differential cross section in the center-of-mass angular range cosθ=−0.985 to +0.40 at six momenta between 1.6 and 2.2 GeV/c in a bubble-chamber experiment. We use the data to look for evidence of direct-channel boson resonances.

Elastic Scattering and Cross Sections in Antiproton-Proton Interactions at 3.3 and 3.7 BeV/c

Ferbel, T. ; Firestone, A. ; Sandweiss, J. ; et al.
Phys.Rev. 137 (1965) B1250-B1255, 1965.
Inspire Record 944963 DOI 10.17182/hepdata.466

The elastic, the pion-production, and the multipion-annihilation cross sections for antiproton-proton interactions at 3.28 and 3.66 BeV/c incident antiproton momenta have been measured. A comparison of the elastic interactions at 3.28 BeV/c with a purely-absorbing disc optical model gave a best value for the radius of interaction of 1.3 F. The real part of the forward scattering amplitude has been found to be less than 20% of the imaginary part. A study of the asymmetries in double elastic scatters yielded a value for a polarizing power of the hydrogen consistent with zero when averaged over production angles.
