Progress in the understanding of neutrino properties

TL;DR

This paper reviews recent progress in understanding neutrino properties, focusing on oscillation results, mixing patterns, and implications for supersymmetry and collider tests.

Contribution

It synthesizes current experimental findings with theoretical models, highlighting new mechanisms for neutrino mass generation and their testability at the LHC.

Findings

Neutrino oscillation results are robust and well-established.

Seesaw mechanisms and supersymmetry offer explanations for neutrino mixing.

Broken R parity models predict testable neutrino signatures at the LHC.

Abstract

I briefly summarize neutrino oscillation results and discuss their robustness. I mention recent attempts to understand the pattern of neutrino mixing within various seesaw mechanisms, with or without supersymmetry and/or 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.
