How did they imagine the creation of tachyons?

Trying to do without the perception through feelings

The searches for a hypothetical tachyon particle were active at the end of the last century. It was expected that when moving through a detector, a charged tachyon would leave no trace because, unlike conventional charged particles, it would interact very weakly with electron shells of atoms of the detector’s active material, leaving the amount of energy not enough for the direct registration. Therefore, the search for tachyon birth in a detector has been done indirectly, by studying such the collisions of energetic charged pions with protons after which the detector saw only an odd number of charged-particle births, implying that the missing unit of charge has been taken away by a tachyon. The detector used was a two-meter-length bubble chamber filled with liquid hydrogen whose atomic nuclei (protons) were colliding with pions flying along the chamber. They have examined hundreds of thousands of asterisks formed by the particles created in the collision points and found only a few dozen appropriate, odd-ray ones. Although there is no direct evidence of the presence of a tachyon among the asterisks selected in such a way, this experiment has shown that the probability of a tachyon birth is less than one ten-thousandth of the probability of creation of any other particles in pion-proton collisions.

In detectors, a charged tachyon would show itself by the absence of a trace of one of the particles that carry the charge from the interaction point.
