Abstract

A two-body Dirac equation is derived from quantum electrodynamics by consideration of crossed and uncrossed photon exchange. The equation is symmetric in the particle labels, and it reduces to the one-body Dirac equation when either particle's mass becomes infinite. The condition that negative-energy states must propagate backward in time is incorporated. Virtual pair contributions are taken into account to leading order in m^-1 in a consistent and nonperturbative manner such that continuum dissolution cannot occur. A straightforward extension provides three-body and N-body equations.
