Theory of neutrino oscillations with entanglement

Creators: Kayser, Boris; Kopp, Joachim; Robertson, R. G. Hamish; Vogel, Petr

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.
