The KATRIN neutrino mass results: An alternative interpretation

TL;DR

This paper offers an alternative interpretation of KATRIN's recent neutrino mass results, which set new upper limits and suggest a best-fit value based on tritium beta decay data.

Contribution

It presents a novel perspective on analyzing KATRIN's data, challenging or complementing the original interpretation of their neutrino mass measurements.

Findings

Proposes an alternative interpretation of KATRIN results

Suggests different implications for neutrino mass constraints

Highlights potential differences in data analysis approaches

Abstract

The KATRIN experiment has recently reported a new upper limit to the mass of the electron neutrino of $m<0.8 eV$ (90\%CL), and a best value of $m^2= 0.26 \pm 0.34 eV^2/c^4$ based on a fit to the observed tritium beta decay spectrum. Here another interpretation of their results is discussed.
