Comment on "Neutrino oscillations originate from virtual excitation of $Z$ bosons" and "Neutrinos produced from $\beta$ decays of neutrons cannot be in coherent superpositions of different mass eigenstates"

TL;DR

This paper refutes recent claims that neutrino oscillations are forbidden by energy conservation and instead confirms they arise from mass mixing, clarifying misconceptions about the underlying physics.

Contribution

It provides a detailed critique of recent assertions denying neutrino oscillations from mass mixing, reaffirming the conventional understanding.

Findings

Neutrino oscillations are consistent with energy conservation.

Oscillations originate from mass eigenstate superpositions, not virtual Z boson exchange.

The recent claims are based on incorrect interpretations of neutrino physics.

Abstract

It was recently claimed (arxiv:2407.00954) that neutrino oscillations through conventional mass mixing are forbidden by energy conservation, and that they in fact arise from virtual $Z$ boson exchange. I explain why both claims, and therefore a repetition of these claims in arxiv:2410.03133, are incorrect.
