A New Family Symmetry: Discrete Quaternion Group
Michele Frigerio
Abstract
We examine the structure of the quaternion group Q8 and its possible application to the physics of flavor. We find that a Q8 family symmetry is suitable to explain the difference between quark and lepton mixing patterns. Distinctive phenomenological predictions are derived for the neutrino sector and the electroweak Higgs sector. We also show how the Q8 symmetry suppresses the effective operators which mediate proton decay.
