Tensions with the Three-Neutrino Paradigm

TL;DR

This paper reviews current inconsistencies in the three-neutrino model, suggesting the potential existence of sterile neutrinos and discussing future experimental approaches to test this hypothesis.

Contribution

It highlights tensions in the standard neutrino framework and explores diverse experimental strategies to definitively probe sterile neutrinos.

Findings

Identifies tensions with the three-neutrino paradigm

Suggests sterile neutrinos as a possible explanation

Proposes future experiments for testing sterile neutrinos

Abstract

We review the tensions with the standard three-neutrino framework for neutrino oscillation. These tensions hint at the possible existence of sterile neutrinos. We briefly describe some of the diverse ideas for probing the existence of such neutrinos in a definitive way through future experiments.
