Propagator Ghosts and Regge Poles
Journal Article

· Journal of Mathematical Physics (New York) (U.S.)
In the approximation of considering only vertex contributions to the propagator, we determine sufficient conditions on the two-particle scattering amplitude which does not generate ghosts in the propagator. The Regge type of behavior does not satisfy these conditions, and will give rise to ghosts unless cancellations occur coming from the higher inelastic contributions to the vertex-function unitarity condition, which have been neglected in our calculation. The double-pole behavior discussed by Frye is found to be the only two-particle scattering-amplitude behavior which will have no propagator ghosts, under certain general conditions.
