Fermion 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...
متن کاملGeneration Symmetry and E6 Unification
The Group E6 for grand unification is combined with the generation symmetry group SO(3)g. The coupling matrices in the Yukawa interaction are identified with the vacuum expectation values of scalar fields which are representations of the generation symmetry. These values determine the hierarchy of the fermions as well as their mixings and CPviolation. This generation mixing appears in conjuncti...
متن کاملUnification in models with replicated gauge groups
We examine unification of gauge couplings in four dimensional renormalizable gauge theories inspired by the latticized (deconstructed) SM or MSSM in five dimensions. The models are based on replicated gauge groups, spontaneously broken to the diagonal subgroup. The analysis is performed at one-loop level, with the contribution from the heavy vector bosons included, and compared with the analogo...
متن کاملPreon Prophecies by the Standard Model
The Standard Model of quarks and leptons is, at first sight, nothing but a set of ad hoc rules, with no connections, and no clues to their true background. At a closer look, however, there are many inherent prophecies that point in the same direction: Compositeness in terms of three stable preons.
متن کاملA Preon Model from Manasson's Theory
V. Manasson has applied dissipative chaos theory to particle physics, deriving a simple relation between the fine structure constant and Feigenbaum delta constant. It is presented a preon model based on Manasson's theory. The model is intended as a naive toy one, as it makes use of unjustified assumptions, as e.g. the possibility of the existence of neither fermionic nor bosonic particles in 3+...
