Abstract
A pair of complex conjugate Regge poles is used to parametrize the contribution of the trajectory and of the cut arising from its coupling with the Pomeranchuk trajectory to the amplitude in charge exchange. It is argued that the previous result of Aviv and Horn, that finite-energy sum rules require additional Regge structure in this amplitude, still holds.
