Possible observation of tachyons associated with extensive air showers


SEVERAL searches1–4 have been made for tachyons using either laboratory particle sources or high energy cosmic rays. Effects associated with their supposed characteristic mass and velocity have been searched for but so far no positive evidence has been reported. As has been repeatedly pointed out, however, the goal of these searches is so important that all possible avenues should be fully investigated. We report here apparently positive results from a pilot search for tachyons associated with cosmic ray showers of energy about 2 × 1015 eV.
