Measurement of the neutral to charged current cross section ratio in neutrino and antineutrino interactions

The authors report on the analysis of inclusive neutral current events produced in neutrino and antineutrino narrow band beams. One finds for incident neutrino energies in the range 12-200 GeV and for hadron energies above 12 GeV a neutral charged current cross-section ratio of R/sub nu /=0.293+or-0...

Sumario:The authors report on the analysis of inclusive neutral current events produced in neutrino and antineutrino narrow band beams. One finds for incident neutrino energies in the range 12-200 GeV and for hadron energies above 12 GeV a neutral charged current cross-section ratio of R/sub nu /=0.293+or-0.010 for incident neutrinos, and R/sub anti nu /=0.35+or-0.03 for antineutrinos. These ratios are consistent with the Weinberg-Salam model, with sin/sup 2/ theta /sub w/=0.24+or-0.02. (6 refs).
