We report on a study of the differential cross section d σ /d y for the processes of elastic ν μ - and ν μ - electron scattering. The data on which this analysis is based were recorded between 1987 and 1990 with the CHARM II detector in the wide band neutrino beam at the CERN-SPS. For the first time the shapes of these y -distributions have been determined in a model-independent way. A fit to the data yields for the squares of the neutral coupling constants the ratio g R 2 / g L 2 =0.60 ± 0.19 (stat.) ± 0.09 (syst.).

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

Barish, B.C. ; Bartlett, J.F. ; Bodek, A ; et al.

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.
