Non-annihilation channels in interactions near centre of mass energy 2200 MeV

Bacon, T.C. ; Butterworth, I. ; Miller, R.J. ; et al.

Nucl.Phys.B 32 (1971) 66-74, 1971.

Inspire Record 1385802 DOI 10.17182/hepdata.33173

The elastic and one-pion production channels from the pp interaction at four c.m. energies between 2150 and 2240 MeV are described. No evidence of formation of the narrow T(2195) meson is observed. The elastic differential cross section is measured in the range of squared four-momentum transfer ¦t¦ > 0.03 GeV2. This has been extrapolated to the forward direction where Re/Im parts of the amplitude are deduced. The one-pion final states are well described by assuming that they are dominated by Δ-production.

Differential Cross-Sections for anti-Proton-Proton Elastic Scattering Between 0.69-GeV/c and 2.43-GeV/c

Eisenhandler, E. ; Gibson, W.R. ; Hojvat, C. ; et al.

Nucl.Phys.B 113 (1976) 1-33, 1976.

Inspire Record 109426 DOI 10.17182/hepdata.8439

Measurements have been made of the differential cross section for p p elastic scattering over a c.m. angular range −0.95 ⩽ cos θ ∗ ⩽ 0.93 at 21 incident antiproton momenta between 0.69 GeV/ c and 2.43 GeV/ c (c.m. energy 1.96–2.58 GeV). About 10 5 events were obtained at each momentum. The results are discussed primarily in terms of the formation of s -channel resonances in the T and U mass regions, and within the context of the optical model of Frahn and Venter.
