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