ResumoThe photon propagator in the Landau gauge is calculated for a U(1) lattice gauge theory. In the confined, strong coupling phase, the propagator resembles that of a massive particle. In the weak coupling phase, the propagator is that of a massless particle. An abrupt change occurs at the transition point. The results are compared to simulations of the gluon propagator in SU(3) lattice gauge theory.
