The exact democratic structure for the quark mass matrix, resulting from the action of the family symmetry group , is broken by the vaccum expectation values o…

An Alternative to See-Saw
J. I. Silva-Marcos
We give a new mechanism for generating very small, and almost degenerate, neutrino masses, without resorting to the see-saw mechanism or unnatural small Yukawa couplings. It requir…
