RELATION BETWEEN VECTOR AND AXIAL-VECTOR CABIBBO ANGLES IN BROKEN SU(3) SYMMETRY,
Abstract
The renormalization of the weak axial-vector coupling constant in the decay of a neutral Xi particle into a Sigma particle (superscript +) + a Beta particle, + a neutrino is calculated on the basis of the assumption that the SU(3) breaking is unimportant at high energies and the result used to show that the equality of the vector and axial-vector Cabibbo angles, which is expected to hold in the limit of exact SU(3) symmetry, is preserved by the symmetry breaking.
