Neutrinonucleon scattering and the dimension of the symmetrybreaking Hamiltonian
Abstract
Some implications of an analysis of neutrinonucleon scattering using Wilson operatorproductexpansions are presented: (A) If the divergence of the axial vector current behaves as a canonical pion field, then there exists an operator of dimension <= 0. (B) A ``maximal contribution assumption'' implies that ∆, the dimension of the SU(3) ⊗ SU(3) breaking Hamiltonian, is >= 2. We also discuss implications for internal symmetry of the vanishing of W_{L}.
