Sterile Neutrinos with Altered Dispersion Relations as an Explanation for Neutrino Anomalies

TL;DR

This paper proposes a model with altered neutrino dispersion relations involving three active and three sterile neutrinos to explain anomalies observed in neutrino oscillation experiments, consistent with existing data.

Contribution

It introduces a novel framework with altered dispersion relations for sterile neutrinos that accounts for experimental anomalies without conflicting with null results in other experiments.

Findings

Explains MiniBooNE and LSND anomalies with sterile neutrinos

Maintains consistency with null results in other neutrino experiments

Provides a new theoretical approach to neutrino oscillation anomalies

Abstract

Recently the MiniBooNE Collaboration has confirmed its anomalous excess in (anti)muon- to (anti)electron-neutrino oscillation data. Combined with long-standing results from the LSND experiment this amounts to a 6.1 sigma evidence for new physics beyond the Standard Model. In this paper we develop a framework with 3 active and 3 sterile neutrinos with altered dispersion relations that provides a mechanism to explain these anomalies without being in conflict with the absence of anomalous neutrino disappearance in other neutrino oscillation experiments.
