Inspire Record 209024 DOI 10.17182/hepdata.30494

Measurements are reported of p̄p total cross sections from 388 to 599 MeV/ c in small momentum steps. Statistical errors are typically ±0.4%and the normalisation uncertainty is ±0.7%. There is no evidence for the “S-meson”.

ANTI-P P TOTAL CROSS-SECTIONS BELOW 420-MEV/C

Bugg, D.V. ; Hall, J. ; Clough, A.S. ; et al.

Phys.Lett.B 194 (1987) 563-567, 1987.

Inspire Record 253124 DOI 10.17182/hepdata.30120

p̄p total cross sections have been measured from 220 to 413 MeV/ c in small (⩽ 10 MeV/ c ) steps of momentum with statistics of ± 0.5 %. There is no evidence for structure in the cross section, and a limit of 8 mb MeV/ c 2 is set with 90% confidence on the strength of any narrow resonance down to 250 MeV/ c .

Observation of Structure in anti-p p and anti-p d Total Cross-Sections Below 1.1-GeV/c

Carroll, A.S. ; Chiang, I.-H. ; Kycia, T.F. ; et al.

Phys.Rev.Lett. 32 (1974) 247, 1974.

Inspire Record 567 DOI 10.17182/hepdata.21309

Total cross sections of p¯p and p¯d have been measured between 360 and 1050 MeV/c, with high statistical precision. Structures are observed in both cross sections at about the same momenta. For p¯p, the central mass is 1932±2 MeV/c2, and a fit to the data with a simple Breit-Wigner resonance plus background gives Γ=9−3+4 MeV/c2. The data suggest that the structures are in the isospin-1 state.

Total Cross-Sections of p and anti-p on Protons and Deuterons Between 50-GeV/c and 200-GeV/c

Carroll, A.S. ; Chiang, I.-H. ; Kycia, T.F. ; et al.

Phys.Rev.Lett. 33 (1974) 928, 1974.

Inspire Record 90202 DOI 10.17182/hepdata.21291

Proton and antiproton total cross sections on protons and deuterons have been measured at 50, 100, 150, and 200 GeV/c. The proton cross sections rise with increasing momentum. Antiproton cross sections fall with increasing momentum, but the rate of fall decreases between 50 and 150 GeV/c, and from 150 to 200 GeV/c there is little change in cross section.
