CP Symmetry and Fermion Masses in O(10) Grand Unification Models
O(10) grand unification models which do not necessarily have an extra global symmetry are discussed, taking the model with one 10-plet in the Yukawa sector as an example. A strong correlation between mass ratios and CP is found. The mass relation mt/mb = vu/vd is recovered when GW = 0; and another special relation mt/mb = GE/GW appears when vd = 0, where GE,W are Yukawa coupling constants and v...
متن کاملGrand Unification of Fermion Masses ∗
After a brief review of the flavour problem we present a new predictive framework based on SUSY SO(10) theory, where the first family plays a role of the mass unification point. The inter-family hierarchy is first generated in a sector of superheavy fermions and then transfered in an inverse way to ordinary quarks and leptons by means of the universal seesaw mechanism. The obtained mass matrice...
متن کاملFermion Masses and Anti-grand Unification
We present an extension of the Standard Model (SM) without supersymmetry, which we use to calculate order of magnitude values for the elements of the mass matrices in the SM. In our model we can fit the 9 quark and lepton masses and 3 mixing angles using only 3 free parameters, with the overall mass scale set by the electroweak interaction. The specific model described here has the anti-grand u...
متن کاملFermion masses, neutrino mixing and CP violation from the anti-grand unification model
The fermion masses and mixing angles are fitted using only 3 free parameters in a non-supersymmetric extension of the Standard Model, with new approximately conserved chiral gauge quantum numbers broken by a set of Higgs fields. The fundamental mass scale of this anti-grand unification model is given by the Planck mass. We also calculate neutrino mixing angles and masses, as well as CP violatio...
متن کاملFermion masses in E6 grand unification with family permutation symmetries
Neutrino masses have been extensively studied in the context of discrete symmetries. A family permutation symmetry easily explains all neutrino oscillations and their mixing angles. However it is not obvious the embedding of such symmetry in a grand unified theory where all fermions live in the same representation. We show that it is possible to embed such a horizontal discrete symmetry in a gr...
