The Golden Ratio Prediction for the Solar Angle from a Natural Model with A5 Flavour Symmetry
Ferruccio Feruglio, Alessio Paris
We formulate a consistent model predicting, in the leading order approximation, maximal atmospheric mixing angle, vanishing reactor angle and tan θ_12 = 1/ϕ where ϕ is the Golden R…
Constraining Flavour Symmetries At The EW Scale II: The Fermion Processes
Reinier de Adelhart Toorop, Federica Bazzocchi, Luca Merlo +1
We study the set of models in which the Standard Model symmetry is extended with the flavour group A4 and there are three copies of the Standard Model Higgs that transform as a tri…
Constraining Flavour Symmetries At The EW Scale I: The A4 Higgs Potential
Reinier de Adelhart Toorop, Federica Bazzocchi, Luca Merlo +1
We consider an extension of the Standard Model in which the symmetry is enlarged by a global flavour factor A4 and the scalar sector accounts for three copies of the Standard Model…
Rare muon and tau decays in A4 Models
Ferruccio Feruglio, Alessio Paris
We analyze the most general dimension six effective Lagrangian, invariant under the flavour symmetry A4 x Z3 x U(1) proposed to reproduce the near tri-bimaximal lepton mixing obser…
Running Effects on Lepton Mixing Angles in Flavour Models with Type I Seesaw
Yin Lin, Luca Merlo, Alessio Paris
We study renormalization group running effects on neutrino mixing patterns when a (type I) seesaw model is implemented by suitable flavour symmetries. We are particularly intereste…
