Duality in Left-Right Symmetric Seesaw Mechanism
E. Kh. Akhmedov, M. Frigerio
We consider type I+II seesaw mechanism, where the exchanges of both right-handed neutrinos and isotriplet Higgs bosons contribute to the neutrino mass. Working in the left-right sy…

A New Family Symmetry: Discrete Quaternion Group
Michele Frigerio
We examine the structure of the quaternion group and its possible application to the physics of flavor. We find that a family symmetry is suitable to explain the differ…

Hybrid Seesaw Neutrino Masses with A_4 Family Symmetry
Shao-Long Chen, Michele Frigerio, Ernest Ma
We consider the scenario in which neutrino data are explained by the interplay of type I and II seesaw terms in the Majorana neutrino mass matrix ${\cal M}_ν= {\cal M}_L - {\cal M}…
