Modelling tri-bimaximal neutrino mixing
M. Hirsch, S. Morisi, J. W. F. Valle
We model tri-bimaximal lepton mixing from first principles in a way that avoids the problem of the vacuum alignment characteristic of such models. This is achieved by using a softl…
S4 as a natural flavor symmetry for lepton mixing
Federica Bazzocchi, Stefano Morisi
Group theoretical arguments seem to indicate the discrete symmetry S4 as the minimal flavour symmetry compatible with tribimaximal neutrino mixing. We prove in a model independent…
Fermion masses and mixing in models with SO(10) x A_4 symmetry
Federica Bazzocchi, Michele Frigerio, Stefano Morisi
We study the flavour sector in models where the three families of matter are unified in a representation of the group. The necessary ingredients to real…
Neutrino Physics and A4 matter assignments
S. Morisi
Tribimaximal lepton mixing can be obtained assuming A4 flavour symmetry. Many possibilities have been explored in the literature and we give a classification in terms of A4 represe…
Tri-bimaximal neutrino mixing and neutrinoless double beta decay
M. Hirsch, S. Morisi, J. W. F. Valle
We present a tri-bimaximal lepton mixing scheme where the neutrinoless double beta decay rate (bb0v) has a lower bound which correlates with the ratio alpha = Dmsol/Dmatm well dete…
Embedding A4 into SU(3)xU(1) flavor symmetry: Large neutrino mixing and fermion mass hierarchy in SO(10) GUT
F. Bazzocchi, S. Morisi, M. Picariello +1
We present a common explanation of the fermion mass hierarchy and the large lepton mixing angles in the context of a grand unified flavor and gauge theory (GUTF). Our starting poin…
