Neutrinos with Z_3 symmetry and new charged-lepton interactions
Ernest Ma
An approximate Z_3 family symmetry is proposed for leptons which results in a neutrino mass matrix with sin^2 2 theta_atm = 1 and tan^2 theta_sol = 0.5, but the latter value could…
The Neutrino Mass Matrix - From A_4 to Z_3
Ernest Ma
With the recent experimental advance in our precise knowledge of the neutrino oscillation parameters, the correct form of the 3 X 3 neutrino mass matrix is now approximately known.…
Tripartite Neutrino Mass Matrix
Ernest Ma
The 3 X 3 Majorana neutrino mass matrix is written as a sum of 3 terms, i.e. M_nu = M_A + M_B + M_C, where M_A is proportional to the identity matrix and M_B and M_C are invariant…
Neutrino Mass and the SU(2)_R Breaking Scale
Ernest Ma
The neutrino sector in a left-right extension of the Standard Model depends on how SU(2)_R is broken. I list all possible scenarios, including the ones where the Majorana nu_R mass…
Quark-Lepton Quartification
K. S. Babu, Ernest Ma, S. Willenbrock
We propose that quarks and leptons are interchangeable entities in the high-energy limit. This naturally results in the extension of [SU(3)]^3 trinification to [SU(3)]^4 quartifica…
The Neutrino Mass Matrix - New Developments
Ernest Ma
With the recent experimental advance in our precise knowledge of the neutrino oscillation parameters, the correct form of the 3 X 3 neutrino mass matrix is now approximately known.…
