A Reggeon Diagram Technique
Abstract
A diagram technique for the analysis of branch points in the complex angular momentum plane is developed from an investigation of the asymptotic behavior of Feynman graphs at high energies and fixed momentum transfer. In this method the reggeon is regarded as a nonrelativistic particle characterized by a two-dimensional momentum k. The pole trajectory a(k2) plays the role of energy, and the angular momentum j plays the role of frequency. The situation arising in the description of the diffraction cone under the assumption of the existence of a Pomeranchuk pole is discussed.
