Abstract
The high-energy behaviour due to contributions from the edge of the hypercontour of integration of a large class of Feynman graphs is determined. It is shown that the sum of the leading terms of graphs with a certain type of iterated structure has a high-energy behaviour consistent with Regge poles which tend tol = −1, −2, −3, ... as the coupling constant tends to zero. Expressions are obtained for the trajectories and residues of these associated Regge poles.
