Abstract:

The prompt electron neutrino and muon neutrino fluxes from proton copper interactions at 400 GeV/c proton momentum have been measured. The asymmetry between the prompt electron (anti) neutrino and the prompt muon (anti) neutrino event rates above 20 GeV is Aeμ = (Ne - Nμ (Nc + Nμ) = 0.07 ± 0.08 corresponding to an Ne/Nμ ratio of 1.14-0.16-0.19. The cross section weighted charge asymmetry for electrons and muons combined is Aνν = 0.15 ± 0.08. The number of D decays into νe and νμ is (4.1 ± 0.9) × 10-4 per incident proton. No evidence for ντ interactions was found. © 1986.

Abstract:

BEBC filled in turn with hydrogen, and with a neon-hydrogen mixture, was exposed to the CERN SPS wide band neutrino and antineutrino beams. The ratios of the charged-current cross sections per nucleon, σ(νH2) σ(νNe) and σ(νH2) σ(νNe), between 20 and 300 GeV were found to be 0.656 ± 0.020 and 1.425 ± 0.052, respectively. Multiplying these ratios by the revised cross sections in neon, σ(νNe) E = (0.723 ± 0.038) × 10-38 cm2/GeV per nucleon and σ(νNe) E = (0.351 ± 0.019) × 10-38 cm2/GeV per nucleon, and their ratio, σ(νNe) σ(νNe) = 0.485 ± 0.020,, yields values for the total charged-current cross sections on protons, σ(νp)/E and σ(νp) E, of (0.474 ± 0.029) × 10-38 cm2/GeV and (0.500 ± 0.032) × 10-38 cm2/GeV. respectively, and a value for the ratio σ(νp) σ(νp) of 1.053 ± 0.066. © 1986.
