Neutrino mass in supersymmetry

TL;DR

This paper reviews neutrino mass generation mechanisms within supersymmetry, including seesaw models and flavor symmetries, and discusses potential experimental tests at the LHC.

Contribution

It provides a comprehensive overview of neutrino mass models in supersymmetry and explores new testable predictions arising from R parity breaking.

Findings

Seesaw mechanisms can operate at high and low scales with or without supersymmetry.

Flavor symmetries offer insights into neutrino mixing patterns.

Broken R parity models predict observable signatures at the LHC.

Abstract

After summarizing neutrino oscillation results I discuss high and low-scale seesaw mechanisms, with or without supersymmetry, as well as recent attempts to understand the pattern of neutrino mixing from flavor symmetries. I also mention the possibility of intrinsic supersymmetric neutrino masses in the context of broken R parity models, showing how this leads to clear tests at the LHC.
