And from the paper[1]: &amp;gt; Therefore, a Lorentz boost can transform a positive-energy tachyon moving forward in time into a negative-energy tachyon moving backward in time. AFAIK, in Feynman diagrams[2], you also specify the initial and final states, and antiparticles are portrayed as moving backwards in time. Is the similarity just superficial or is there more to it?
