Using Neutrino Oscillations to Measure $H_0$?

TL;DR

This paper argues that using neutrino oscillations to measure the Hubble constant is unfeasible because oscillations average out over cosmological distances, leaving only mixing angles to influence the probability.

Contribution

It demonstrates the impracticality of using cosmic neutrino oscillations for H_0 measurement due to averaging effects over large distances.

Findings

Oscillations average out over cosmological distances.

Oscillation probability depends only on mixing angles.

Measuring H_0 via neutrino oscillations is unfeasible.

Abstract

Recently, the idea of using neutrino oscillations to measure the Hubble constant was introduced. We show that such a task is unfeasible because for typical energies of cosmic neutrinos, oscillations average out over cosmological distances and so the oscillation probability depends only on the mixing angles.
