Current-Algebra Sum Rules in Neutrino Scattering and Scale Dimension of the Chiral-Symmetry-Breaking Hamiltonian

Current-algebra sum rules for the structure functions W₄ and W₅ which occur in neutrino scattering because of the nonconservation of the axial-vector current are derived and used to get information about the scaling behavior of W₄ and W₅. This information together with the light-come analysis is used to determine the scale dimension of the chiral-symmetry-breaking Hamiltonian.
