Neutrino physics and non-standard interactions

TL;DR

This paper discusses how non-standard interactions of neutrinos could lead to misidentification of their flavor and challenges in distinguishing neutrinos from antineutrinos, impacting future neutrino experiments.

Contribution

It highlights the phenomenological consequences of new neutrino interactions, emphasizing their potential to affect experimental interpretations.

Findings

Non-standard neutrino interactions can cause flavor misidentification.

Such interactions may hinder the ability to distinguish neutrinos from antineutrinos.

Implications for future neutrino experimental analyses.

Abstract

In most of the proposals for new physics beyond the standard model, neutrinos have new interactions and some of them have phenomenological consequences that, although at present they may seem purely academic, probably will have to be taken into account in the future neutrino experiments. Here we show that new interactions may imply the misidentification of the flavour of the neutrinos, and the experimental ability to distinguish neutrinos from antineutrinos.
