Breaking flavor democracy with symmetric perturbations

Flavor democracy broken in the fermion mass matrix by means of small perturbations can give rise to hierarchical fermion masses. We study the breaking of the S3L×S3R symmetry associated with democratic mass matrices to a smaller exchange symmetry S2L×S2R in the charged lepton, up and down quark sect...
