Evaluation of Multiloop Diagrams via Lightcone Integration
Y. J. Feng, C. S. Lam
Abstract
We present a systematic method to determine the dominant regions of internal momenta contributing to any two-body high-energy near-forward scattering diagram. Such a knowledge is used to evaluate leading high-energy dependences of loop diagrams. It also gives a good idea where dominant multiparticle cross sections occur.
