TwoBody Dirac Equation and Its WFO
Abstract
A relativistic equation is proposed for the bound state of two particles, which is in accord with the boundary condition for the propagation of the negativeenergy states and reduces to the (onebody)Dirac equation in the infinite limit of one of the constituent mass. It also has the symmetries to assure the existence of the antiboundstate with the same mass. The interaction kernel(pseudopotential) is systematically constructed by diagonalizing the Hamiltonian of the background field theory, by which the retardation effects are included in the interaction. Its wave function at the origin(WFO) behaves properly in a manner sugested by the covariant field theory.
