MiniBooNE, MINOS+ and IceCube data imply a baroque neutrino sector

TL;DR

This paper explores how nonstandard neutrino interactions within a 3+1 scheme could reconcile experimental anomalies from MiniBooNE, MINOS+, and IceCube, suggesting a more complex neutrino sector than previously thought.

Contribution

It proposes that nonstandard interactions can resolve discrepancies among neutrino experiments within the 3+1 framework.

Findings

Nonstandard interactions can reconcile MiniBooNE with MINOS+ and IceCube data.

The neutrino sector may be more complex than the standard 3-flavor model.

Some datasets or assumptions might need revision for consistency.

Abstract

The 4.8$\sigma$ anomaly in MiniBooNE data cannot be reconciled with MINOS+ and IceCube data within the vanilla framework of neutrino oscillations involving an eV-mass sterile neutrino. We show that an apparently consistent picture can be drawn if charged-current and neutral-current nonstandard neutrino interactions are at work in the 3+1 neutrino scheme. It appears that either the neutrino sector is more elaborate than usually envisioned, or one or more datasets needs revision.
