Flavour physics without flavour symmetries [PDF]

Physical Review D, 2017
We quantitatively analyze a quark-lepton flavour model derived from a six-dimensional supersymmetric theory with $SO(10)\times U(1)$ gauge symmetry, compactified on an orbifold with magnetic flux.

Modular flavour symmetries and modulus stabilisation

Journal of High Energy Physics, 2022
We study the problem of modulus stabilisation in the framework of the modular symmetry approach to the flavour problem. By analysing simple UV-motivated CP-invariant potentials for the modulus τ we find that a class of these potentials has (non-fine ...

Modular flavour symmetry and orbifolds

Journal of High Energy Physics, 2023
We develop a bottom-up approach to flavour models which combine modular symmetry with orbifold constructions. We first consider a 6d orbifold 𝕋2 /ℤ N , with a single torus defined by one complex coordinate z and a single modulus field τ, playing the role

6d SCFTs and U(1) flavour symmetries [PDF]

Journal of High Energy Physics, 2018
We study the behaviour of abelian gauge symmetries in six-dimensional N = (1,0) theories upon decoupling gravity and investigate abelian flavour symmetries in the context of 6d N = (1, 0) SCFTs.

Combining Pati-Salam and Flavour Symmetries [PDF]

Journal of High Energy Physics, 2015
We construct an extension of the Standard Model (SM) which is based on grand unification with Pati-Salam symmetry. The setup is supplemented with the idea of spontaneous flavour symmetry breaking which is mediated through flavon fields with ...

CP and discrete flavour symmetries [PDF]

Journal of High Energy Physics, 2013
We give a consistent definition of generalised CP transformations in the context of discrete flavour symmetries. Non-trivial consistency conditions imply that every generalised CP transformation can be interpreted as a representation of an automorphism of the discrete group.

Tri-Bimaximal Neutrino Mixing and Discrete Flavour Symmetries [PDF]

Fortschritte der Physik, 2012
We review the application of non-Abelian discrete groups to Tri-Bimaximal (TB) neutrino mixing, which is supported by experiment as a possible good first approximation to the data.

Discrete flavour symmetries from the Heisenberg group

Physics Letters B, 2016
Non-abelian discrete symmetries are of particular importance in model building. They are mainly invoked to explain the various fermion mass hierarchies and forbid dangerous superpotential terms.

Accidental Peccei–Quinn symmetry from discrete flavour symmetry and Pati–Salam

Physics Letters B, 2018
We show how an accidental U(1) Peccei–Quinn (PQ) symmetry can arise from a discrete A4 family symmetry combined with a discrete flavour symmetry Z3×Z52, in a realistic Pati–Salam unified theory of flavour. Imposing only these discrete flavour symmetries,

Flavour Symmetry Embedded - GLoBES (FaSE-GLoBES) [PDF]

Computer Physics Communications, 2021
Neutrino models based on flavour symmetries provide the natural way to explain the origin of tiny neutrino masses. At the dawn of precision measurements of neutrino mixing parameters, neutrino mass models can be constrained and examined by on-going and up-coming neutrino experiments.
