The only other persons that I'm aware of was (1) dono, and his assertions were clearly false, too, and (2) Athel, who criticized where the paper was published and who wrote it rather than on the content of the paper. > Like too many others, you seem unable to comprehend legitimate > criticism of your pet notions to which you have devoted years of your life. Pot, kettle, black Prok. Your two criticisms were false. In the first one you claimed u > c^2/v cannot mean that a tachyon becomes undetectable because all particles must be observable in a frame. The answer to your criticism: Of course, an observer must use instruments to observe particles, so a method of observing particles which have u > c^2/v was described in the very paper that you were criticizing: DOI: 10.13189/ujpa.2023.170101. Your second criticism was that that imaginary mass means that tachyons have imaginary energy and momentum. This, of course, is also false. Discerning physicists know that imaginary mass of tachyons was hypothesized to counter an imaginary sqrt(1 - u^2/c^2) in the denominator of equations for energy and momentum when u > c. This was the BASIC proposal by Bilaniuk et al (19620 which allowed tachyon energy and momentum to be real. As for dono asserting that "effective mass" measured in beta decay experiments wasn't the "true" mass of neutrinos, this is basically correct, but it's an insignificant difference. He was quite confused about how the neutrino eigenvalues correspond to the neutrino flavors and the mechanics of the measurement of m_eff^2. He had some other wild assertions, but they were nonsense. In any case, I know of no legitimate criticisms. SO these are the only "criticisms" of DOI: 10.13189/ujpa.2023.170101 (other than Athel's which was, basically, a type of attack on the messenger rather than the message). So if you are aware of any other criticisms, I would really like to know about them. The only type of criticism that is possible, IMHO, is that it's classical physics rather than quantum physics. I believe that QFT has a long way to go to be able to deal properly with tachyons. A recent paper has come the closest to doing this: "Covariant quantum field theory of tachyons" Phys. Rev. D, 110, 015006, (2024). DOI: 10.1103/PhysRevD.110.015006. arXiv:2308.00450v2. They have a rather extensive history of previous attempts at quantization of tachyons and why they failed.
