Flavour symmetries in a renormalizable SO(10) model
Nuclear Physics B, 2016 In the context of a renormalizable supersymmetric SO(10) Grand Unified Theory, we consider the fermion mass matrices generated by the Yukawa couplings to a 10⊕120⊕126‾ representation of scalars. We perform a complete investigation of the possibilities of

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 ...

Flavour and CP symmetries in the inverse seesaw
European Physical Journal C: Particles and Fields, 2022 We consider an inverse seesaw mechanism of neutrino mass generation in which the Standard Model is extended by $$3+3$$ 3 + 3 (heavy) sterile states, and endowed with a flavour symmetry $$G_f$$ G f , $$G_f=\Delta (3 \, n^2)$$ G f = Δ ( 3 n 2 ) or $$G_f ...

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

The flavour puzzle and flavour symmetries
, 2017 The presence of approximate flavour symmetries is invoked to make New Physics models near the TeV scale compatible with the very demanding quark flavour violation tests. These tests pose a serious threat for any acceptable Standard Model extension at the TeV scale, motivated by naturalness issues.

Flavour physics, flavour symmetries, supersymmetry and unification
Nuclear Physics B - Proceedings Supplements, 1997 Abstract While solving the supersymmetric flavour problem, a U(2) flavour symmetry might be at the origin of the pattern of fermion masses and mixings. The consequences of this hypothesis are spelled out concerning the parameters of the CKM matrix and their observability in B - and K -physics. The relevance of searching for lepton flavour violation

Charged lepton flavour violation from inverse seesaw with flavour and CP symmetries
Nuclear Physics BWe study charged lepton flavour violation in a scenario in which light neutrino masses are generated via the inverse seesaw mechanism with 3+3 gauge singlet fermions, Ni and Sj, i,j=1,2,3.

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.

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.
