# 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 SU3 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 SU3 symmetry, is preserved by the symmetry breaking.
