Total cross sections of K± and p¯ on hydrogen and deuterium were measured in a standard transmission experiment with statistical precisions of the order of 0.05-0.25%. Data were obtained in the momentum range 2.45-3.30 GeV/c for K−N, 1.55-3.30 GeV/c for K+N, and 1.00-3.30 GeV/c for p¯N. Cross sections for the pure isotopic spin states are obtained using a procedure for the deuterium data which takes into account Fermi motion and the shadow effect. Evidence for the following new structures was found: Y1*(2455), Y1*(2620), Y0*(2585), Z1*(2150), Z1*(2500), π1*(2290), π1*(2350), and π0*(2375).

Measurement of p- p and p- d total cross-sections at 3.00 gev/c

In a new measurement of proton total cross sections at 3.00 GeV/c, the p−d total cross section is found to be lower than a previous measurement by 1.17±0.09 mb. This implies a corresponding new value for the total cross section for I=0 which is 2.18±0.27 mb lower than the previous value. Possible sources of systematic error are discussed.

Inspire Record 84768 DOI 10.17182/hepdata.28072

Measurements have been carried out of total cross sections of positive kaons on hydrogen and deuterium to a statistical precision of better than ± 0.1 mb for most points in the range of laboratory momentum from 410 to 1065 MeV / c in intervals of approximately 50 MeV/ c . A very broad elastic structure in the I = 0 state is inferred.

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

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.

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.

Structures in K- Nucleon Total Cross-Sections Below 1.1-GeV/c

Total cross sections of K−p and K−d have been measured between 410 and 1070 MeV/c with high statistical precision. In addition to the well known Λ(1520), Λ(1820), and Σ(1769), we confirmed the presence of the Λ(1692) and the Σ(1670). We have also observed several structures which could be Y* resonances: Λ(1646), Λ(1735), Σ(1583), Σ(1608), Σ(1633), and Σ(1715).

Production of Dimuons in 16-GeV/c pi p Interactions

Bunnell, K. ; Duong-van, Minh ; Kogan, E. ; et al.
Phys.Rev.Lett. 40 (1978) 136, 1978.
Inspire Record 121404 DOI 10.17182/hepdata.20920

A clear, prompt dimuon signal has been observed in a low-statistics streamer-chamber experiment with 16-GeV/c πp interactions. The good mass resolution makes it possible to identify the contributions from ρ and ω decays and η and ω Dalitz decays. An excess of events is observed in the mass region ∼400-600 MeV which is not accounted for by the above-mentioned decays.

Exclusive Vector Meson Production in Muon - Proton Scattering

Phys.Rev.D 19 (1979) 1303, 1979.
Inspire Record 130570 DOI 10.17182/hepdata.24312

From a muon-proton scattering experiment with a streamer chamber at the Stanford Linear Accelerator we present results in the ranges 0.3<Q2<4.7 GeV2 and 1.7<W<4.7 GeV for the reactions μ+p→μpV where V is a vector meson (ρ0, ω, or φ). It is shown that in ρ production the skewing parameter and the longitudinal-transverse ratio change significantly as Q2 increases above 1 GeV2. The cross section for ρ0 production as a function of Q2 falls below the vector-meson-dominance prediction. The ratio of the cross section for exclusive vector-meson production to the total cross section falls by a factor of 10 between photoproduction and a Q2 of 2 GeV2, yet the ratio of ω to ρ production remains constant at the photoproduction value out to Q2>2 GeV2.
