“…Here again, only upper limits were found, although an initial 1974 report by Roger Clay and Philip Crouch reported seeing "possible" evidence for tachyons in the form of many pulses in the detectors in advance of the shower front [9]. The same group, however, using an improved electronics system, failed to reproduce their earlier results, which was also the case in subsequent searches by other groups conducted during the 1970s and early 1980s [10][11][12][13][14][15][16][17]. A much more recent search in 2020 similarly found no evidence in cosmic ray data [18].…”

Here, we review searches for empirical evidence for the existence of tachyons, superluminal particles having m2<0. The review considers searches for new particles that might be tachyons, as well as evidence that neutrinos are tachyons from data that 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 newly identified results.

“…High-energy accelerator experiments also find a very few e+e-+3y events at 30 and 80 GeV and the rate agrees with QED theory when detector thresholds are properly accounted for (Femandez, 1987;Martyn, 1990; L3 Collab, 1990;Opal Collab, 1991) . The complication of detector threshold sensitivity combined with the complexity of cosmic-ray showers precludes a quantitative analysis of triplet state e+eannihilation rates in the previous tachyon cosmic-ray searches (Marini, 1982;Bhat, 1979;Bartlett, 1978;Smith, 1977;Prescott, 1976;Hazen, 1975;Clay, 1974). However, we have discussed this problem with Prof. Wayne Hazen (Hazen, 1975) who explained that these experiments were not analyzed for the fundamental processes (as we desire) but rather, to simply disprove the Clay and Crouch (Clay, 1974) positive tachyon result.…”

Tachyons are hypothetical particles that travel faster than the vacuum speed of light. Previous experiments have searched for, but have not found evidence of tachyons. Long-standing, anomalous measurements of the orthopositronium (o-Ps) decay rate are interpreted as evidence for two tachyons being occasionally emitted when o-Ps decays. Restricting the coupling of tachyon pairs to a single photon (no tachyon coupling to matter) yields a new theory where tachyons are only observed in o-Ps decay and not in the previous tachyon experiments. Combining the single photon coupling theory with all previous experiments predicts that these tachyons must deposit energy while traversing scintillator detectors. A new tachyon search experiment will use this energy loss prediction to attempt to find tachyons passing through the apparatus or set limits disproving the original o-Ps to tachyon hypothesis. Viewing an intense o-Ps source, a time-of-flight spectrometer uses the superluminal property of tachyons for identification. Several months of continuous data acquisition will be necessary to completely eliminate the o-Ps to tachyon hypothesis.
