Status of Neutrino Theory

TL;DR

This paper reviews the current status of neutrino theory, discussing oscillation results, mass generation mechanisms, flavor understanding, and implications for supersymmetry, LHC tests, leptogenesis, and dark matter.

Contribution

It provides a comprehensive overview of neutrino mass theories, highlighting potential experimental tests and recent theoretical developments.

Findings

Neutrino oscillation results confirm flavor mixing.

Supersymmetric models may offer testable neutrino mass origins at the LHC.

Connections between neutrino masses, leptogenesis, and dark matter are discussed.

Abstract

A summary of neutrino oscillation results is given along with a discussion of neutrino mass generation mechanisms, including high and low-scale seesaw, with and without supersymmetry, as well as recent attempts to understand flavor. I argue that if the origin of neutrino masses is intrinsically supersymmetric, it may lead to clear tests at the LHC. Finally, I briefly discuss thermal leptogenesis and dark matter.
