REMARKS ON THE EQUAL-TIME COMMUTATOR OF AXIAL-VECTOR CURRENT COMPONENTS.
Abstract
The matrix element of the equal-time commutator of the axial-vector current and its fourth component between one-nucleon states of the same momentum is investigated on the basis of very general principles. The dependence on the pion 4-momentum of Adler-Weisberger type relations for the renormalization of the axial-vector coupling constant is examined. Furthermore, the connection of Schwinger terms antisymmetric in the isospin indices with subtractions in the involved scattering amplitudes is shown. (Author)
