Is there a 4.5 PeV neutron line in the cosmic ray spectrum?
R. Ehrlich
Abstract
Recently we presented a model to fit the cosmic ray spectrum using the hypothesis that the electron neutrino is a tachyon. The model predicted the existence of a neutron flux in the cosmic rays in a narrow region centered on E = 4.5 +/- 2.2 PeV. The published literature on Cygnus X-3 reveals just such a 6σ spike of neutral particles centered on E = 4.5 PeV. A second prediction of the model concerning integrated neutron fluxes at several energies also is consistent with published data. A specific further test of the model is proposed.
