Abstract

Measurements of coherent π0 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 View the MathML source 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 π0 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.
