Tritium Decay and the Hypothesis of Tachyonic Neutrinos
Early discovery. Linked by one identifiable commenter. This paper is outside the main ranking; a mention is not an endorsement.
Abstract
Numerous recent measurements indicate an excess of counts near the endpoint of the electron energy spectrum in tritium decay. We show that this effect is expected if the neutrino is a tachyon. Results of calculations, based on a unitary (causal) theory of tachyons, are presented. The hypothesis of tachyonic neutrinos also offers a natural explanation of the V-A structure of the weak leptonic current in neutrino interactions.
This is an old hypothesis: http://arxiv.org/abs/hep-ph/9810355
