Flavour symmetries in a renormalizable SO(10) model [PDF]

open access: yesNuclear 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

FCNC-free multi-Higgs-doublet models from broken family symmetries [PDF]

open access: yesPhysics Letters B, 2020
We demonstrate how residual flavour symmetries, infrared signatures of symmetry breaking in complete models of flavour, can naturally forbid (or limit in a flavour specific way) flavour-changing neutral currents (FCNC) in multi-Higgs-doublet models (MHDM)

Two A4 modular symmetries for Tri-Maximal 2 mixing [PDF]

open access: yesNuclear Physics B, 2022
We construct a lepton flavour model based on two A4 modular symmetries. The two A4 are broken by a bi-triplet field to the diagonal A4 subgroup, resulting in an effective modular A4 flavour symmetry with two moduli. We employ these moduli as stabilisers,

Flavour and CP symmetries in the inverse seesaw [PDF]

open access: yesEuropean 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 ...

The flavour puzzle and flavour symmetries [PDF]

open access: yes, 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.

Discrete flavour symmetries from the Heisenberg group

open access: yesPhysics 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]

open access: yesComputer 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.
