Boson Propagators On The Light Front
Propagator
The propagator for a gauge boson in a gauge theory depends on the choice of convention to fix the gauge. For the gauge used by Feynman and Stueckelberg, the propagator for a photon is − . The propagator for a massive vector field can be derived from the Stueckelberg Lagrangian.
