Solutions to the Atmospheric Neutrino Problem

TL;DR

This paper reviews the current status of the atmospheric neutrino anomaly and discusses various proposed solutions, including neutrino oscillations, flavor-changing interactions, and neutrino decay, highlighting their implications.

Contribution

It provides a comprehensive overview of different theoretical explanations for the atmospheric neutrino problem, comparing standard and alternative models.

Findings

Neutrino oscillations are a leading explanation for the anomaly.

Alternative scenarios like flavor-changing interactions are also considered viable.

Neutrino decay presents a possible non-oscillation solution.

Abstract

In this talk I review the present status of the atmospheric neutrino anomaly and discuss some solutions that have been presented in the literature to solve this problem. In particular I review the "standard" solution in terms of neutrino oscillations as well as alternative scenarios such as the possibility of flavour changing neutrino interactions with the Earth and neutrino decay.
