High-energy behavior of non-Abelian gauge theories

This paper is a detailed account of a study in perturbation theory of the high-energy behavior of non-Abelian gauge theories. We calculate the fermion-fermion scattering amplitude up to sixth order in the coupling constant in the high-energy limit $s\to \infty$ with fixed $t$, in the approximation of keeping only the leading logarithmic terms. Our results indicate that the high-energy behavior of non-Abelian gauge theories are complicated, and quite different from the known behaviors of other field theories studied so far.
