Abstract
"Six observations based on data and fits to data from a variety of areas are consistent with the
hypothesis that the electron neutrino is a m2 νe = −0.11±0.016eV 2 tachyon. The data are from areas
including CMB fluctuations, gravitational lensing, cosmic ray spectra, neutrino oscillations, and 0ν
double beta decay. For each of the six observations it is possible under explicitly stated assumptions
to compute a value for m2 νe, and it is found that the six values are remarkably consistent with the above cited νe mass (χ2 = 2.73). There are no known observations in clear conflict with the claimed result."
