Neutrino Anomalies without Oscillations

TL;DR

This paper reviews alternative explanations for three neutrino anomalies that do not rely solely on conventional oscillation models, highlighting the need for non-zero neutrino masses in some cases.

Contribution

It introduces and discusses explanations beyond standard neutrino oscillations for the solar, atmospheric, and LSND anomalies, expanding the theoretical landscape.

Findings

Some anomalies can be explained without oscillations.

Non-zero neutrino masses are necessary in certain models.

Alternative theories may complement or challenge standard oscillation explanations.

Abstract

I review explanations for the three neutrino anomalies (solar, atmospheric and LSND) which go beyond the ``conventional'' neutrino oscillations induced by mass-mixing. Several of these require non-zero neutrino masses as well.
