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