Query: Lepton U_l(1) symmetry and interaction of neutrinos with deuterons at
  high energies   The following items are discussed: 1. The lepton U_l(1) symmetry and its
relation to the presence of the neutrino mass term in the Hamiltonian. 2. The
possibility of the measurement of the neutrino-deuteron reactions with high
energy neutrinos at SNO by using neutrinos from a neutrino factory. 3. The weak
axial one-boson exchange currents for the Bethe-Salpeter equation.
