# Neutrino oscillations in accelerated frames

## TL;DR

This paper explores how neutrino oscillations are affected by uniform acceleration, introducing a covariant phase definition and analyzing inertial effects, with implications for atmospheric neutrinos and extreme acceleration scenarios.

## Contribution

It presents a covariant framework for neutrino oscillations in accelerated frames, extending the standard formalism to include inertial effects and energy redshift.

## Key findings

- Inertial effects modify the Pontecorvo formula for neutrino oscillations.
- Energy redshift plays a key role in accelerated frame oscillations.
- Preliminary phenomenological analysis suggests observable effects in atmospheric neutrinos.

## Abstract

We discuss neutrino oscillations in vacuum from the point of view of a uniformly accelerated observer. A covariant definition of quantum phase is introduced with the aim of generalizing the standard expression of the oscillation amplitude to the accelerating frame. By way of illustration, we address a simplified two-flavor model with relativistic neutrinos, showing that inertial effects on the usual Pontecorvo formula are intimately related to the energy redshift. Phenomenological aspects are preliminarily analyzed in the context of atmospheric neutrinos. Finally, we discuss a gedanken experiment in order to investigate our formalism in regime of extreme acceleration.
