Description
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 determine the cross sections sigmasub(ν) = (96+-42).10-40 cm2 and sigmaanti ν = (79+-26).10-40 cm2 per average marble nucleus. Comparing these experimental results to theoretical predictions we evaluated the isovector axial vector neutral-current coupling constant vertical strokeβvertical stroke = 1.08+-0.24, averaged over the neutrino and 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 vertical strokeβvertical stroke = 1.10+-0.23 is derived.
