摘要：

In the scattering of electronic neutrinos νe by electrons, charged- and neutral-current weak interactions can interfere with each other. According to all the popular gauge models that are consistent with neutralcurrent data, including the measurements of polarized-electron-deuteron scattering, this interference should be negative. The conditions under which a beam-dump experiment can be used to study charged- and neutralcurrent interference are studied in detail. It appears that if the interference is assumed to be present in the first place, then a 25% measurement of the integrated cross section will allow one to determine its sign. Greater accuracy is required to show that the interference actually does occur in νe-e scattering. Tests for the presence of the helicity-flipping covariants S, P, T are also discussed. © 1979 The American Physical Society.
