Abstract

Measurements of coherent π 0 production by muon-neutrinos and antineutrinos on nuclei in marble have been carried out using the CHARM neutrino detector in the CERN-SPS neutrino wide-band beam. We determined the cross sections σ ν = (96±42)×10 −40 cm 2 and σ ν = (79±26)×10 −40 cm 2 per average marble nucleus. Comparing these experimental results to theoretical predictions we evaluated the isovector axial vector neutral-current coupling constant ∣ β ∣ = 1.08±0.24, averaged over the neutrino and the antineutrino results, and found agreement with the prediction of the standard model, β = 1.0. From the ratio of coherent π 0 production by neutral-current interactions observed in this experiment and of coherent π − production by charged-current interactions of antineutrinos measured in BEBC a value of ∣ β ∣ = 1.10±0.23 is derived.
