Abstract:

Using the UA2 apparatus, the inclusive cross section has been measured for production of high-pT direct photons in p̄p collisions at s=546 GeV and s=630 GeV. The results are in good agreement with QCD predictions. © 1986.

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.
