Natural Science Forum / Physics / Particle Physics / July 2008klein gordon eq for virtual particles
hi, Is there a klein gordon equation describing virtual particles? For example if I take a virtual photon, then will putting (D^2 - m^2)\psi describe the virtual photon? I'm not feeling comfortable with the above since it describes a massive "real" boson, instead of a virtual photon. thanks ganesh On Jul 29, 1:14 am, gans1...@rediffmail.com wrote: > hi, > Is there a klein gordon equation describing virtual particles?

Does it have to be necessarily imaginary? As long as E^2 - p^2 = m^2 is not satisfied (where m = rest mass of the real particle) its virtual...I guess. So, for a photon, if E^2 - p^2 is not equal to zero, its virtual. So, E can be real, and E^2 - p^2 > 0 should still be describing a virtual photon. ganesh |
