On a theory of neutrino oscillations with entanglement

TL;DR

This paper demonstrates that a quantum entanglement-based approach to neutrino oscillations produces the standard oscillation wavelength, clarifying why simpler plane-wave models also yield correct results despite their approximations.

Contribution

It introduces an entanglement-focused theoretical framework for neutrino oscillations that aligns with traditional results and explains the validity of plane-wave approximations.

Findings

Entanglement approach reproduces standard oscillation wavelength

Plane-wave models yield correct results despite simplifications

Provides insight into localization effects in neutrino oscillations

Abstract

We show that, despite appearances, a theoretical approach to neutrino oscillation in which the neutrino and its interaction partners are entangled yields the standard result for the neutrino oscillation wavelength. We also shed some light on the question of why plane-wave approaches to the neutrino oscillation problem can yield the correct oscillation wavelength even though they do not explicitly account for the localization of the neutrino source and the detector.
