Quark masses, mixings, and CP violation from spontaneous breaking of flavor SU(3)3
Abstract
A GF=SU(3)Q×SU(3)u×SU(3)d invariant scalar potential breaking spontaneously the quark flavor symmetry can explain the standard model flavor puzzle. The approximate alignment in flavor space of the vacuum expectation values of the up and down "Yukawa fields" is explained as a dynamical effect, and the observed quark mixing angles, the weak CP violating phase, and hierarchical quark masses can be reproduced without introducing hierarchical parameters.
