Form Invariance and Symmetry in the Neutrino Mass Matrix
E. I. Lashin, S. Nasri, E. Malkawi +1
We present the general form of the unitary matrices keeping invariant the Majorana neutrino mass matrix of specific texture suitable for explaining oscillation data. In the case of…
(Z_2)^3 Symmetry of the Tripartite Model
E. I. Lashin, E. Malkawi, S. Nasri +1
We derive in a simple way the symmetry which characterizes uniquely the phenomenologically successful tripartite form leading to the tribimaximal mixing in the neutrino m…
Neutrino Oscillations Due to Nonuniversal Gauge Interactions in the Weak Sector
Ehab Malkawi
We discuss the structure of the neutrino mass matrix as derived from a nonuniversal electroweak gauge interaction model. We discuss two interesting patterns of neutrino masses. The…
A Light Sterile Neutrino in the TopFlavor Model
Ehab Malkawi, E. I. Lashin, Hatem Widyan
A scenario based on the TopFlavor model is presented to explain the origin of a light sterile neutrino as indicated by all combined neutrino oscillation experiments. The model is p…
New Physics in the Third Family and its Effect on Low Energy Data
Ehab Malkawi, C. -P. Yuan
We investigate, in detail, a model in which the third family fermions are subjected to an SU(2) dynamics different from the first two families. Constrained by the precision Z-pole…
Low Energy Data and a Model of Flavor Mixing
Ehab Malkawi, C. -P. Yuan
We consider a model in which the third family fermions are subjected to an SU(2) interaction different from the first two family fermions. Constrained by the Z-pole data, the heavy…
