Gravity tidings from domain walls: Flavour hierarchies are making waves
Stefan Antusch, Ivo de Medeiros Varzielas, Miguel Levy
Explaining the observed charged fermion mass hierarchies points to flavour symmetries inducing a suppression of the lighter species' masses. When the symmetries are global, it is e…
3HDM with softly broken and
Gonçalo Barreto, Ivo de Medeiros Varzielas
We perform an analysis of the scalar sector of 3-Higgs doublet models with softly broken and symmetries. We consider the various vacuum expectation value alignments…
Modular flavoured Pati-Salam model with two family seesaw
A. E. Cárcamo Hernández, Ivo de Medeiros Varzielas, S. F. King +1
We present a unified model of quarks and leptons with modular flavour symmetry, where the two lightest family masses are naturally suppressed via a Pati-Salam version of the…
Softly-broken or 3HDMs with stable states
Ivo de Medeiros Varzielas, Diogo Ivo
We study multi-Higgs models with a triplet of or symmetry that is softly-broken. Focusing on parameters that softly break the respective symmetries but preserve the dir…
Exploring multi-Higgs models with softly broken large discrete symmetry groups
Ivo de Medeiros Varzielas, Igor P. Ivanov, Miguel Levy
We develop methods to study the scalar sector of multi-Higgs models with large discrete symmetry groups that are softly broken. While in the exact symmetry limit, the model has ver…
framework for cobimaximal neutrino mixing models
A. E. Cárcamo Hernández, Ivo de Medeiros Varzielas
We propose a simple framework based on that leads to the successful cobimaximal lepton mixing ansatz, thus providing a predictive explanation for leptonic mixing observable…
