... gauge theory - the SU_c(3) × SU(2) × U(1) × SU_f(3) standard model. In addition to QCD and electroweak (EW) phase transitions there is other SU_f(3) family phase transition occurring near the familon masses, maybe above the EW scale (that is, above 1 TeV). One motivation is that in our Universe ther ...

... anything. It’s just that our choice of a ground state “hides” or “breaks” the obvious reflection symmetry of the original Lagrangian. What about the spontaneous part? If you think about it, the choice of a ground state is completely arbitrary in this system. There is no external agency that favors o ...
