Lepton mass matrix from double covering of A <sub>4</sub> modular flavor symmetry*

چکیده
Abstract We study a double covering of modular flavor symmetry. To this end, we construct lepton models for canonical and radiative seesaw scenarios. Using irreducible doublet representations, heavier Majorana fermion masses are characterized by one free parameter that would differentiate from Through χ square numerical analysis, demonstrate both scenarios produce some predictions in case normal hierarchy reproducing neutrino oscillation data. However, no solution satisfies the data inverted hierarchy.

Lepton Family Symmetry and Neutrino Mass Matrix
The standard model of leptons is extended to accommodate a discrete Z3 × Z2 family symmetry. After rotating the charged-lepton mass matrix to its diagonal form, the neutrino mass matrix reveals itself as very suitable for explaining atmospheric and solar neutrino oscillation data. A generic requirement of this approach is the appearance of three Higgs doublets at the electroweak scale, with obs...
متن کاملNeutrino Mass Matrix with Approximate Flavor Symmetry
Phenomenological implications of neutrino oscillations implied by recent experimental data on pattern of neutrino mass matrix are diss-cussed. It is shown that it is possible to have a neutrino mass matrix which shows approximate flavor symmetry; the neutrino mass differences arise from flavor violation in off-diagonal Yukawa couplings. Two modest extensions of the standard model, which can emb...

متن کاملLepton Mass Matrix Models
The smallness and hierarchy in fermion parameters could be the result of selection rules due to an Abelian horizontal symmetry broken by a small parameter. When applied to the lepton sector, then for a large class of models, a number of interesting order of magnitude relations arise: with i < j, m(ν i)/m(ν j) ∼ sin 2 θ ij ; m(ℓ − i)/m(ℓ − j) < ∼ sin θ ij ; m(ν i)/m(ν j) > ∼ m 2 (ℓ − i)/m 2 (ℓ −...
متن کاملS4 as a natural flavor symmetry for lepton mixing
Group theoretical arguments seem to indicate the discrete symmetry S4 as the minimal flavor symmetry compatible with tribimaximal neutrino mixing. We prove in a model-independent way that indeed S4 can realize exact tribimaximal mixing through different symmetry breaking patterns. We present two models in which lepton tribimaximal mixing is realized in different ways and for each one we discuss...
