A Supersymmetric Solution to the Solar and Atmospheric Neutrino Anomalies

TL;DR

This paper proposes a supersymmetric framework explaining solar and atmospheric neutrino anomalies through lepton family number violating interactions affecting neutrino flavor change in matter.

Contribution

It develops a formalism for neutrino flavor change via lepton number violation in a three-neutrino context and applies it to explain observed neutrino anomalies.

Findings

Lepton family number violating interactions can account for neutrino flux anomalies.

The model explains zenith dependence in atmospheric neutrino data.

Proposes a supersymmetric solution to longstanding neutrino puzzles.

Abstract

The formalism for neutrino flavor change induced by lepton family number violating interactions is developed for the three-neutrino case, and used to derive the corresponding flavor change probabilities in matter. Applied to the solar and atmospheric neutrino fluxes, it is argued that the observed anomalies, including the zenith dependence for the atmospheric case, could be due to such interactions.
