Implications for the Cosmic Ray Spectrum of a Negative Electron Neutrino (Mass)2
Abstract
The hypothesis that the electron neutrino is a tachyon with |m|=sqrt(-m2) = 0.5 eV/c2 is consistent with certain properties of the cosmic ray spectrum, including: the existence of a change in power law (the "knee") at E = 1015 eV, the E-3 power law after the knee, another change in power law (the "ankle") at E = 1019 eV, the changes in composition above the knee, the change in anisotropy at the knee, and the absence of a GZK cutoff above E = 4 x 1019 eV. The hypothesis predicts a substantial flux of cosmic ray neutrons in a narrow energy region just above the knee of the spectrum.
