Contribution

It provides a comprehensive review of tachyon searches and introduces new results related to the 3+3 neutrino model with a tachyonic component.

Findings

Empirical support for a tachyonic neutrino mass state

Analysis of neutrino data suggesting superluminal properties

Review of searches for tachyons in particle physics

Abstract

Here we review empirical evidence for the possible existence of tachyons, superluminal particles having m^2 < 0: The review considers searches for new particles that might be tachyons, as well as evidence that neutrinos are tachyons from data which may have been gathered for other purposes. Much of the second half of the paper is devoted to the 3 + 3 neutrino model including a tachyonic mass state, which has empirical support from a variety of areas. Although this is primarily a review article, it contains several new results.
