The proper time path-integral representation for the two-body Green's function is derived for several examples of field theory, e.g., the \(\varphi^{3}\) theory in \(4 d\), scalar and spinor QED, and its properties are studied in the quenched approximation. The perturbative expansion is shown to coi
