Quantum chromodynamics and other field theories on the light cone
TL;DR: In this paper, the light-cone quantization of quantum field theory has been studied from two perspectives: as a calculational tool for representing hadrons as QCD bound states of relativistic quarks and gluons, and also as a novel method for simulating quantum field theories on a computer.

Conformal properties of four-gluon planar amplitudes and Wilson loops
TL;DR: In this paper, it was shown that all the momentum integrals appearing in the perturbative on-shell calculations up to four loops are dual to true conformal integrals, well defined off shell.

MHV amplitudes in N=4 super Yang-Mills and Wilson loops
TL;DR: For one-loop MHV amplitudes with an arbitrary number of external legs this universal function can be derived using Wilson loops as mentioned in this paper, which is in precise agreement with the known expression for the infinite sequence of MHV amplitude in N = 4 super-Yang-Mills.

On planar gluon amplitudes/Wilson loops duality
TL;DR: In this paper, an explicit two-loop calculation of the Wilson loop dual to the four-gluon scattering amplitude was performed and it was shown that the relation holds beyond one loop.

Conformal Ward identities for Wilson loops and a test of the duality with gluon amplitudes
TL;DR: In this paper, the conformal symmetry of the gauge theory, broken by cusp anomalies, was used to derive anomalous conformal Ward identities valid to all loops and show that they uniquely fix the form of the finite part of a Wilson loop with n cusps (up to an additive constant) for n=4n=4 and 5 and reduce the freedom in it to a function of conformal invariants for n⩾6n⩽6.

Light-cone superspace and the ultraviolet finiteness of the N=4 model
TL;DR: In this paper, it was shown that the N = 4 model is completely free of ultraviolet divergences in any order of perturbation theory, and that the β-function vanishes in any θ-function in any light-cone frame.

Renormalization of the Wilson loops beyond the leading order
TL;DR: In this article, the renormalization properties of the Wilson loops containing cusp singularities were investigated in the limit of large and small cusp angles, and the relation of these results to the non-leading infrared behaviour of the quark form factor was demonstrated.

Gauge fields as rings of glue
TL;DR: In this article, the authors take the view that gauge fields can be considered as chiral fields on a loop space, both in classical and in quantum theories, and derive the equations of motion governing the propagation of the infinitely thin rings formed by the lines of color-electric flux.

Exponentiation of eikonal cross sections in nonabelian gauge theories
TL;DR: In this paper, a theorem generalising the exponentiation property of eikonal cross sections in abelian gauge theories to the nonabelian case has been presented which generalises the well-known exponentiation properties of cross sections.
