Abstract

Differential cross sections of the neutrino splitting of a deuteron due to both charged (1) and neutral (2) weak currents are obtained in analytical form. Within the framework of the Weinberg-Salem model for currents of the first kind (CFK) and additional assumptions regarding currents of the second kind (CSK), in the case of dipole parameterization of the nucleon form factors, the dependence of the cross sections of processes (1) and (2) on q2 with E v =1 and 2 GeV is studied by means of a computer. It is shown that the relative contribution of CSK to the cross section (with respect to CFK) is ∿1–3%, measurement of dependence of the cross section on q2, with the aim of detecting CSK, may be expediently conducted, for process (1), in the range 0.1 GeV2 < q2 < 0.2 GeV2, since the cross section reaches a maximum in this range. For process (2), the cross section monotonically decreases with rise in q2, and it may be measured in any region where q2 > 0.1 GeV2, since the contribution of CSK is practically the same anywhere above this value.
