U(1) flavour symmetries as Peccei-Quinn symmetries [PDF]
Journal of High Energy Physics, 2019 We investigate to what extent a generic, generation-dependent U(1) symmetry acting on the quark Yukawa operators can reduce the number of free parameters by forcing some entries in the Yukawa matrices to vanish.

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 symmetries in the SMEFT [PDF]
Journal of High Energy Physics, 2020 We analyse how U(3)5 and U(2)5 flavour symmetries act on the Standard Model Effective Field Theory, providing an organising principle to classify the large number of dimension-six operators involving fermion fields. A detailed counting of such operators,

Flavour Symmetry Embedded -- GLoBES (FaSE-GLoBES) [PDF]
Computer Physics Communications, 2020 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.

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.
