Ann E. Nelson, Jonathan Walsh
TL;DR
This paper proposes a neutrino oscillation model with sterile neutrinos and a new gauge boson to explain experimental anomalies, predicting outcomes for upcoming MiniBooNE results.
Contribution
It introduces a novel model combining sterile neutrinos and a light gauge boson to reconcile conflicting neutrino oscillation experiment results.
Findings
Reconciles LSND and MiniBooNE results within the new model.
Predicts a low energy excess of electron neutrino events at MiniBooNE.
Provides parameter ranges consistent with experimental data.
Abstract
We consider a model of neutrino oscillations with three additional sterile neutrinos and a gauged B-L interaction. We find allowed values of the model parameters which can reconcile the results of the evidence for antimuon neutrino to antielectron neutrino conversion seen at the LSND neutrino oscillation experiment with the null results of the MiniBooNE experiment. A portion of the low energy excess of electron neutrino events seen at MiniBooNE can arise naturally, and we make a quantitative prediction for the forthcoming anti-neutrino oscillation results at MiniBooNE.
