Quark, lepton and neutrino masses in grand unified theories with local generation group

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

We investigate unified models where all small quantities in the fermion mass matrices are given in terms of one small ratio of symmetry breaking scales. We describe for a U(1) generation symmetry how the size of masses and mixings is determined, including possible contributions from heavy mirror quarks and leptons. This can be used for computerized model scanning. We search for realistic mass patterns in anomaly-free SU(5) × U(1)G models and find several examples. Interesting patterns for neutrino masses can be obtained.
