Abstract

Abstract Within a gauge theory based on the gauge group SU 2 × SU 2 × U 1 and on the four quark flavours u, d, s, and c the Cabibbo angle is calculated in terms of the quark mass ratios. The u and d quark masses are zero in the absence of weak interaction mixing due to the existence of a discrete symmetry R. The calculated value of the Cabibbo angle is in agreement with the observed value.
