Observation of A Meson x --> 2 gamma, with Mass 2.85-GeV/c**2, Produced in the Charge Exchange Reaction pi- p --> x n at 40-GeV/c

Apel, W.D. ; Augenstein, K.H. ; Bertolucci, E. ; et al.
Phys.Lett.B 72 (1978) 500-502, 1978.
Inspire Record 122151 DOI 10.17182/hepdata.27481

The invariant mass spectrum of neutral final states produced in π − p charge-exchange scattering at 40 GeV/ c has been studied, searching for heavy particles decaying in 2γ. A peak is observed around 2.85 GeV/ c 2 . The cross section of the reaction π − p→X(2.85)+n, times the branching ratio of the X→2 γ decay, is measured to be σ × BR ⋍ 2 × 10 −34 cm 2 .

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.

Inclusive Baryon Production in e+ e- Annihilation

Piccolo, M. ; Peruzzi, I. ; Luke, D. ; et al.
Phys.Rev.Lett. 39 (1977) 1503, 1977.
Inspire Record 121395 DOI 10.17182/hepdata.20965

The inclusive production of antiprotons and Λ's in e+e− annihilation has been measured as a function of the c.m. energy in the range 3.7-7.6 GeV. We find that the baryon cross section has a behavior different from the total hadronic production. Our results show a rapid rise in the ratio σp¯σμμ between 4.4 and 5 GeV, consistent with what would be expected from charmed baryon production. Λ¯ production is 10-15% of p¯ production at all energies.

Total Cross-Sections for Charged Current Neutrino and anti-neutrino Interactions in BEBC in the Energy Range 20-GeV to 200-GeV

The Aachen-Bonn-CERN-London-Oxford-Saclay collaboration Bosetti, P.C. ; Deden, H. ; Deutschmann, M. ; et al.
Phys.Lett.B 70 (1977) 273, 1977.
Inspire Record 121301 DOI 10.17182/hepdata.27526

The charged-current cross sections for neutrinos and antineutrinos on nucleons in the energy range 20–200 GeV are given. Taken in conjunction with the previous Gargamelle results, they show that σ E is almost constant with energy for antineutrinos, and falls with energy for neutrinos. The value of 〈q 2 〉 E decreases with energy for both neutrinos and antineutrinos, and these deviations from exact Bjorken scaling are consistent with those observed in electron and muon inelastic scattering. We find no evidence for new heavy quark states with right-handed coupling.

Normalized Small Y Cross-Sections for Neutrinos and anti-neutrinos at High-Energy

Barish, B.C. ; Bartlett, J.F. ; Bodek, A ; et al.
Phys.Rev.Lett. 39 (1977) 741, 1977.
Inspire Record 5717 DOI 10.17182/hepdata.50114

We present results on flux-normalized neutrino and antineutrino cross sections near y=0 from data obtained in the Fermilab narrow-band beam. We conclude that values of σ0=dσdy|y=0 are consistent with rising linearly with energy over the range 45<~Eν<~20.5 GeV. The separate averages of ν and ν¯, each measured to 4%, are equal to well within the errors. The best fit for the combined data gives σ0E=(0.719±0.035)×10−38 cm2/GeV at an average Eν of 100 GeV.

A Comparison of K+- n Charge Exchange Reactions at 8.5-GeV/c and 13-GeV/c

Gilchriese, M.G.D. ; Dunwoodie, W.M. ; Fieguth, T.H. ; et al.
Phys.Rev.Lett. 40 (1978) 6, 1978.
Inspire Record 120363 DOI 10.17182/hepdata.20886

The cross sections for the line-reversed reaction pairs K+n→K0p and K−p→K¯0n, and K+p→K0Δ++ and K−n→K¯0Δ− have been determined with high statistics and good relative normalization at 8.36 and 12.8 GeV/c in a spectrometer experiment at Stanford Linear Accelerator Center. The cross sections for the K+-induced reactions are larger than for the K−, contrary to the expectations of weakly-exchange-degenerate Regge-pole models. The ratio of the reaction cross sections is about the same as at lower energies and shows little change with momentum transfer.
