    Graduate Tachyonic Energies in a Minkowski Metric

    I figured it out. I found my energy-momentum for tachyons to be given by E^2=p^2-m^2.

    Yes, you're right. I was about to change it. Thanks for noting.

    Graduate Tachyonic Energies in a Minkowski Metric

    So I'm working on a problem (Hartle problem 6, chapter 6) dealing with tachyons. So far, I have determined the four-velocity and the four-momentum (up to a sign) of a tachyon. I have, with the four-velocity being a unit spacelike four-vector, u^{\alpha}=\frac{\pm...
