Abstract

Antineutrino interactions in BEBC are compared to look for differences between the differential cross sections per nucleon in neon and in deuterium. The identical geometries, beam spectra and muon identification criteria and acceptances allow comparison with very small systematic errors. The results are compared in detail with μ and e scattering data from EMC and SLAC. We find no rise in the ratio dσ/dx (ν Ne)/σ/dx (ν D2) at low x, independent of Q2 up to Q2 ∼ 14 GeV2. © 1984., 0, 58 auteurs, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

The ratios Rvp and Rvp of the neutral current to charged current cross sections for neutrino and antineutrino interactions on protons have been measured in BEBC. The beam was the CERN SPS 400 GeV wideband beam. The bubble chamber, equipped with the standard External Muon Identifier, was surrounded with an additional plane of wire chambers (Internal Picket Fence), which was added to improve neutral current event identification. For a total transverse momentum of the charged hadrons above 0.45 GeV/c and a charged multiplicity of at least 3, it was found that Rvp = 0.384 ± 0.015 and Rvp = 0.338 ± 0.014 ± 0.016, corresponding to a value of sin 2 θ w (M w MS of 0.225 ± 0.030 . Combining the results from hydrogen and an isoscalar target, the differences of the neutral current chiral coupling constants were found to be u2l−d2L = −0.080 ± 0.043 ± 0.012 and u2R−d2R = 0.021±0.055±0.028.
