High-Energy Behavior of Feynman Amplitudes. II. Nonplanar Graphs

Abstract

A method previously developed by the author for obtaining the asymptotic behavior of Feynman integrals associated with planar graphs in the $\lambda {\phi }^3$ theory is extended for the study of nonplanar graphs. The results are discussed in connection with the high-energy behavior of amplitudes and the associated properties in the complex angular momentum plane.
