Quark Mass Ratios and Mixing Angles from SU(3) Family Gauge Symmetry
We explore a framework for the computation of quark mass ratios and CKM mixing angles based on an SU(3) family gauge symmetry. The four ratios md/mb, ms/mb, mu/mt, and mc/mt can be fit at one-loop in the family gauge interaction. The same is true of the quark mixing angles theta12 and theta23, although the result for theta13 is too small. The CP violating phase is naturally O(1).
