# Flavor neutrino states for pedestrians

## TL;DR

This paper examines the theoretical foundations of neutrino flavor states, advocating for defining them as eigenstates of flavor charges to ensure logical consistency in describing neutrino production and detection.

## Contribution

It proposes a logically consistent definition of neutrino flavor states as eigenstates of flavor charges, addressing a theoretical gap in the understanding of neutrino oscillations.

## Key findings

- Supports defining flavor states as eigenstates of flavor charges
- Highlights the importance of a consistent theoretical framework
- Reviews basic facts about neutrino flavor states

## Abstract

In this paper we discuss the ontology of flavor states of oscillating neutrinos. While an heuristic approach to this subject, experimentally successful in the high energy regime, is generally adopted, a logically consistent definition of flavor states describing neutrinos produced and detected in weak processes is still desirable and essential from a theoretical perspective. Here we briefly review basic facts and present some arguments which suggest that the definition of flavor states as eigenstates of flavor charges is the most reasonable one.
