Quantum coherence between mass eigenstates of a neutrino cannot be destroyed by its mass-momentum entanglement

Abstract

In the latest of a series of papers (arXiv:2410.21850), it has been claimed that neutrinos cannot oscillate as a consequence of their mass mixing. I clarify that this arises from the unrealistic assumption that neutrinos will always be in nearly exact eigenstates of energy, and ignoring the spatial dependence of the neutrino wave function. Taking into account the latter, neutrinos will be observed to oscillate in precisely the expected manner.
