Some aspects of non-Abelian gauge theories
… thesis we consider two aspects of the theory of non-Abelian gauge fields. In the first part,we calculate the fermion-fermion scattering amplitude for a non-Abelian gauge theory with SU(N) gauge symmetry in the limit of high energy with fixed momentum transfer through sixth order in the coupling …

TOPICS IN QUANTUM FIELD THEORY
<p>A gauge invariant action functional for non-abelian gauge theories is derived from the vacuum to vacuum transition amplitude. This effective action is then examined in the loop expansion, where it is demonstrated that the unrenormalized one-loop term is equal to the change in the zero point …

Quantum Chromodynamics with Eight and Twelve Degenerate Quark Flavors on the Lattice
This thesis is concerned with the behavior of non-abelian gauge theories with many flavors of fermions. In perturbation theory, an infrared fixed point is predicted to exist, and theories become conformal in the low energy limit, in non-abelian gauge theories with the number of fermions just below …
