Modular Symmetry With Three-Moduli and Flavor Problem
Mohammed Abbas, Shaaban Khalil
The modular symmetry with three moduli is investigated. We assign different moduli to charged leptons, neutrinos, and quarks. We analyze these moduli at their fixed points wh…
Neutrino Masses and Deviation from Tri-bimaximal mixing in Δ(27) model with Inverse Seesaw Mechanism
M. Abbas, S. Khalil, A. Rashed +1
We propose a scheme, based on Δ(27) flavor symmetry and supplemented by other discrete symmetries and inverse seesaw mechanism, where both the light neutrino masses and the deviati…
Fermion masses and mixing in flavour model
Mohammed Abbas, Shaaban Khalil
An extension of the Standard Model (SM) based on the non-Abelian discrete group is considered. The flavour symmetry is spontaneously broken only by gauge singlet sc…
The (Z_2)^3 symmetry of the non-tri-bimaximal pattern for the neutrino mass matrix
E. I. Lashin, M. Abbas, N. Chamoun +1
In view of the recent neutrino oscillation data pointing to a non-vanishing value for the smallest mixing angle (), we derive and find explicit realizations of the f…
Is the tri-bimaximal mixing accidental?
Mohammed Abbas, A. Yu. Smirnov
The Tri-bimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We…
Neutrino masses, mixing and leptogenesis in TeV scale B-L extension of the standard model
M . Abbas, S. Khalil
We address the issue of the neutrino masses and mixing in TeV scale extension of the Standard Model. We show that if Dirac neutrino masses are of order Gev, then th…
