Vacuum alignment in SUSY A 4 models
In this note we discuss the vacuum alignment in globally supersymmetric models with spontaneously broken flavour symmetries in the presence of generic soft supersymmetry (SUSY) breaking terms. We show that the...

A SUSY GUT of flavour with S 4 × SU(5) to NLO
We construct a Supersymmetric (SUSY) Grand Unified Theory (GUT) of Flavour based on S 4 × SU(5), together with an additional (global or local) Abelian symmetry, and study it to next-to-lea...

Leptons in holographic composite Higgs models with non-abelian discrete symmetries
We study leptons in holographic composite Higgs models, namely in models possibly admitting a weakly coupled description in terms of five-dimensional (5D) theories. We introduce two scenarios leading to Majora...

General lepton mixing in holographic composite Higgs models
We introduce a scenario of lepton mixing in holographic composite Higgs models based on non-abelian discrete symmetries of the form G f = X × Z N ...

Article
Lepton mixing parameters from discrete and CP symmetries
We consider a scenario with three Majorana neutrinos in which a discrete, finite flavour group G f is combined with a generalized CP transformation. We derive c...

Open AccessA realistic pattern of lepton mixing and masses from \(S_4\) and CP
We present a supersymmetric model with the flavour symmetry \(S_4 \times Z_3\) ...

Open AccessLepton mixing from the interplay of the alternating group A5 and CP
Assuming three generations of Majorana neutrinos, we study the different mixing patterns that arise from the non-trivial breaking of the flavor group A5 and CP to the residual symmetries Z3, Z5 or Z2 × Z2 in the ...

Open AccessUnification of gauge couplings in radiative neutrino mass models
We investigate the possibility of gauge coupling unification in various radiative neutrino mass models, which generate neutrino masses at one- and/or two-loop level. Renormalization group running of gauge coup...

Open AccessPhenomenology of the generalised scotogenic model with fermionic dark matter
We study a simple extension of the Standard Model that accounts for neutrino masses and dark matter. The Standard Model is augmented by two Higgs doublets and one Dirac singlet fermion, all charged under a new...
