Trimaximal neutrino mixing from scotogenic A4 family symmetry

We propose a flavor theory of leptons implementing an A(4) family symmetry. Our scheme provides a simple way to derive trimaximal neutrino mixing from first principles, leading to simple and testable predictions for neutrino mixing and CP violation. Dark matter mediates neutrino mass generation, as in the simplest scotogenic model. (c) 2021 The Author(s). Published by Elsevier B.V.

Automated summary

The proposed flavor theory of leptons incorporates an A(4) family symmetry and allows for the derivation of trimaximal neutrino mixing from first principles, leading to straightforward and testable predictions for neutrino mixing and CP violation. This theory posits that dark matter mediates neutrino mass generation, similar to the simplest scotogenic model.
