3 neutrino mass experiments fit a strange 3 + 3 model, but will KATRIN reveal the model's unique 3-part signature?

TL;DR

This paper discusses a novel 3+3 neutrino mass model supported by experimental data and suggests that the KATRIN experiment could uniquely confirm or refute this model's distinctive three-part signature.

Contribution

It introduces an unconventional 3+3 neutrino mass model supported by multiple data sources and predicts a specific signature for KATRIN to test this model.

Findings

Support for the 3+3 model from SN 1987A analysis

Support from dark matter fits

Potential KATRIN signature to confirm or reject the model

Abstract

Evidence is presented in support of an unconventional $3+3$ model of the neutrino mass eigenstates with specific $m^2>0$ and $m^2<0$ masses. The two large $m^2>0$ masses of the model were originally suggested based on a SN 1987A analysis, and they were further supported by several dark matter fits. The new evidence for one of the $m^2>0$ mass values comes from an analysis of published data from the $\emph{three}$ most precise tritium $\beta-$decay experiments. The KATRIN experiment by virtue of a unique 3-part signature should either confirm or reject the model in its entirety.
