Abstract
We give a new mechanism for generating very small, and almost degenerate, neutrino masses, without resorting to the seesaw mechanism or unnatural small Yukawa couplings. It requires the existence of at least 4 families with an almost democratic structure for the Yukawa couplings. It is also proven that this structure can account for large lepton mixings of the three light leptons.Keywords
