A Predictive Superunification SO ( 10 ) × ∆ 48 ( SU ( 3 ) ) × U ( 1 ) Model for Fermion Masses and Mixings

چکیده
Based on a few basic assumptions, a predictive supersymmetric grand unification G U = SO(10) × ∆ 48 (SU (3)) × U (1) model is proposed. Thus, all the observed 45 chiral fermions with additional 3 right-handed neutrinos are unified into an irreducible triplet 16-dimensional spinor representation of G U. Electroweak symmetry breaking naturally requires two Higgs doublets which belong to a single 10 representation of SO(10). The model provides an unified description for all the Yukawa and gauge couplings. With a given structure of the physical vacuum, the fermion masses and mixings are predicted in terms of two basic parameters.

Fermion masses and mixing angles are studied in an SUSY SO(10) × ∆(48) × U (1) model with small tan β. Thirteen parameters involving masses and mixing angles in the quark and charged lepton sector are successfully predicted by a single Yukawa coupling and three ratios of VEVs caused by necessary symmetry breaking. Ten relations among the low energy parameters have been found with four of them f...

Assuming universality of Yukawa coupling of the superpotential and maximal spontaneous CP violation, fermion masses and mixing angles including that of neutrinos are studied in an SUSY SO(10)×∆(48)× U(1) model with small tan β. The low energy parameters of the standard model are determined solely by the Clebsch factors of the symmetry group and the structure of the physical vacuum. Thirteen par...

متن کاملThe Flavour Puzzle from an Orbifold GUT Perspective
Neutrino masses and mixings are very different from quark masses and mixings. This puzzle is a crucial hint in the search for the mechanism which determines fermion masses in grand unified theories. We study the flavour problem in an SO(10) GUT model in six dimensions compactified on an orbifold. Three sequential families are localized at three branes where SO(10) is broken to its three GUT sub...
