On Deviations from Bimaximal Neutrino Mixing
The PMNS neutrino mixing matrix UPMNS is in general a product of two unitary matrices Ulep and Uν arising from the diagonalization of the charged lepton and neutrino mass matrices, UPMNS = U † lepUν . Assuming that Uν is a bimaximal mixing matrix, we investigate the possible forms of Ulep. We identify three possible generic structures of Ulep, which are compatible with the existing data on neut...
متن کاملTri-bimaximal and bimaximal neutrino mixing from discrete sym- metries
— The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently it has been shown that also the bimaximal pattern could be a very good starting point in order to describe the lepton mixing. In this paper I review both the flavour structures and then I present an explicit example. 1. – The lepton mixing matrix The solar and the atmospheric neutrino anomalies are well ex...
متن کاملTri-bimaximal Neutrino Mixing from Orbifolding
We show that the A4 discrete symmetry that naturally leads to tri-bimaximal neutrino mixing can be simply obtained as a result of an orbifolding starting from a model in 6 dimensions. This particular orbifolding has four fixed points where 4 dimensional branes are located and the tetrahedral symmetry of A4 connects these branes. In this approach A4 appears after the reduction from six to four d...
متن کاملType II See–Saw Mechanism, Deviations from Bimaximal Neutrino Mixing and Leptogenesis
A possible interplay of both terms in the type II see–saw formula is illustrated by presenting a novel way to generate deviations from exact bimaximal neutrino mixing. In type II see–saw mechanism with dominance of the non–canonical SU(2)L triplet term, the conventional see–saw term can give a small contribution to the neutrino mass matrix. Nevertheless, if the triplet term corresponds to the b...
متن کاملDeviations from Tri-bimaximal Neutrino Mixing in Type-II Seesaw and Leptogenesis
Current experimental data allow the zero value for one neutrino mass, either m1 = 0 or m3 = 0. This observation implies that a realistic neutrino mass texture can be established by starting from the limit (a) m1 = m2 = 0 and m3 6= 0 or (b) m1 = m2 6= 0 and m3 = 0. In both cases, we may introduce a particular perturbation which ensures the resultant neutrino mixing matrix to be the tri-bimaximal...
