Large-Angle Pion-Proton Elastic Scattering at High Energies

Orear, J. ; Rubinstein, R. ; Scarl, D.B. ; et al.

Phys.Rev. 152 (1966) 1162-1170, 1966.

Inspire Record 50774 DOI 10.17182/hepdata.407

Differential cross sections for elastic π±−p scattering have been measured at lab momenta of 8 and 12 GeV/c in a momentum-transfer region corresponding to 1.2≤−t≤6 (GeV/c)2. Also, differential cross sections near 180° were measured for 4 and 8 GeV/c pions. At momentum transfers greater than −t=2 (GeV/c)2, the π−p cross sections drop much faster with increasing angle than the corresponding p−p cross sections. Also, in the region −t≃1.3 (GeV/c)2, there is structure in the π−p angular distribution but not in the p−p angular distribution. At −t≃3 (GeV/c)2, the drop in cross section appears to stop and from then on the angular distribution is consistent with isotropy. But in the angular region 170° to 180°, the cross sections have become much larger, and sharp backward peaks are observed. Information is given on the energy and charge dependences and widths of these backward peaks.

Discontinuous behaviour in large angle proton-proton elastic scattering at high energies

Allaby, J.V. ; Cocconi, G. ; Diddens, A.N. ; et al.

Phys.Lett.B 25 (1967) 156-159, 1967.

Inspire Record 1389227 DOI 10.17182/hepdata.754

Measurements of elastic proton-proton differential cross sections for angles between 65° and 90° c.m.s. have been made at 8, 9, 10, 11, 14, 15 and 21 GeV/c. The shape of the angular distribution is found to change suddenly between 8 and 11 GeV/c. An interpretation of this discontinuous behaviour in terms of the reactive effects of baryon-antibaryon pair production is proposed.

Proton-proton Elastic Scattering at 8.35 BeV

Seb, Do In ; Kirillova, L.F. ; Shafranova, M.G. ;

Sov.Phys.JETP 17 (1963) 1000-1003, 1963.

Inspire Record 1387687 DOI 10.17182/hepdata.69225

A more accurate value is obtained for the differential cross section for pp scattering at 8.35 BeV by measurement in photographic emulsions. It is found that the cross section is greater than cited in previous communications [ 3 - 5 ] in a large range of angles. The data are analyzed on the basis of the Regge pole technique and compared with those of other experiments. The total pp elastic scattering cross section is found to be 10.8 :1: 0.8 mb; the mean square interaction radius is (1.07 :1: 0.08) F.
