Partial symmetry from kinetic normalization
N. Chamoun, C. Hamzaoui, M. Toharia
We consider models with broken - permutation symmetry through higher dimensional operators renormalizing the lepton kinetic terms in the action. We study the consequences on…
Role of unphysical neutrino phases in the phenomenology of consistently defined textures. Case study: traceless neutrino mass matrix
N. Chamoun, E. I. Lashin
We highlight the role played by the unphysical phases in the definition of neutrino mass matrix, showing it does not relate to mere semantics, rather it has an effect on the phenom…

N. Chamoun, E. I. Lashin
We study a texture of neutrino mass matrix characterized by two constraints consisting of one equality and another antiequality between two elements corresponding to two pairs of t…

A. Ismael, E. I. Lashin, N. Chamoun
We present a full phenomenological and analytical study for the neutrino mass matrix characterized by two vanishing subtraces. We update one past result in light of the…

A. Ismael, M. AlKhateeb, N. Chamoun +1
We consider a texture for the neutrino mass matrix characterized by one vanishing subtrace. We analyze phenomenologically and analytically all the six possible patterns,…
Phase broken symmetry and the neutrino mass hierarchy
N. Chamoun, C. Hamzaoui, S. Lashin +2
Inspired by the neutrino oscillations data, we consider the exact symmetry, implemented at the level of the neutrino mass matrix, as a good initial framework around which to…

E. I. Lashin, N. Chamoun, C. Hamzaoui +1
We find a realization of the -symmetry in the neutrino mass matrix which expresses a rotation of the symmetry and is able to impose a generic smallest mixing angle, in c…
Neutrino Mixing and Leptogenesis in Symmetry
E. I. Lashin, N. Chamoun, C. Hamzaoui +1
We study the consequences of the -symmetry behind the -- universality in neutrino mass matrix. We then implement this symmetry in the type-I seesaw mechanism and show ho…
Neutrino Mass Textures and Partial - Symmetry
E. I. Lashin, N. Chamoun, C. Hamzaoui +1
We discuss the viability of the -- interchange symmetry imposed on the neutrino mass matrix in the flavor space. Whereas the exact symmetry is shown to lead to textures of co…
The U(1) symmetry of the non-tribimaximal pattern in the degenerate mass spectrum case of the neutrino mass matrix
E. I. Lashin, N. Chamoun, S. Nasri
On account of the new neutrino oscillation data signalling a non-zero value for the smallest mixing angle (), we present an explicit realization of the underlying U(1) symmetr…
