HYPOTHESIS OF TACHYONIC NEUTRINOS

Anomalies observed in the electron energy spectrum in tritium decay ar e expected if electron (anti)neutrino is a tachyon; in particular anha ncement of counts near the end point leading to negative values for th e electron antineutrino mass squared. Since the tachyonic neutrino fie ld is an eigenstate of the helicity operator, the hypothesis of tachyo nic neutrinos offers a natural explanation of the V-A structure of the weak leptonic current. Our 'educated guess' for the mass of a hypothe tical tachyonic neutrino is approximate to 5 eV.
