Scattering amplitudes, Wilson loops and the string/gauge theory correspondence

LF Alday, R Roiban - Physics reports, 2008 - Elsevier
We review, in a self-contained and pedagogical manner, recent developments and
techniques for the evaluation of scattering amplitudes of planar N= 4 SYM theory at both …

Gluon scattering amplitudes at strong coupling

LF Alday, J Maldacena - Journal of High Energy Physics, 2007 - iopscience.iop.org
We describe how to compute planar gluon scattering amplitudes at strong coupling in Script
N= 4 super Yang Mills by using the gauge/string duality. The computation boils down to …

Comments on operators with large spin

LF Alday, J Maldacena - Journal of High Energy Physics, 2007 - iopscience.iop.org
We consider high spin operators. We give a general argument for the logarithmic scaling of
their anomalous dimensions which is based on the symmetries of the problem. By an …

We give a representation of the parity-even part of the planar two-loop six-gluon maximally
helicity violating (MHV) amplitude of N= 4 super-Yang-Mills theory, in terms of loop …

Comments on gluon scattering amplitudes via AdS/CFT

LF Alday, J Maldacena - Journal of High Energy Physics, 2007 - iopscience.iop.org
In this article we consider n gluon color ordered, planar amplitudes in Script N= 4 super
Yang Mills at strong't Hooft coupling. These amplitudes are approximated by classical …

Hexagon Wilson loop= six-gluon MHV amplitude

JM Drummond, J Henn, GP Korchemsky, E Sokatchev - Nuclear Physics B, 2009 - Elsevier
We compare the two-loop corrections to the finite part of the light-like hexagon Wilson loop
with the recent numerical results for the finite part of the MHV six-gluon amplitude in N= 4 …

Maximally supersymmetric planar Yang-Mills amplitudes at five loops

Z Bern, JJM Carrasco, H Johansson… - Physical Review D …, 2007 - APS
We present an Ansatz for the planar five-loop four-point amplitude in maximally
supersymmetric Yang-Mills theory in terms of loop integrals. This Ansatz exploits the recently …

A supermatrix model for = 6 super Chern-Simons-matter theory

N Drukker, D Trancanelli - Journal of High Energy Physics, 2010 - Springer
We construct the Wilson loop operator of\(\mathcal {N}\)= 6 super Chern-Simons-matter
which is invariant under half of the supercharges of the theory and is dual to the simplest …

Space-time S-matrix and Flux tube S-matrix II. Extracting and Matching Data

B Basso, A Sever, P Vieira - Journal of High Energy Physics, 2014 - Springer
A bstract We elaborate on a non-perturbative formulation of scattering amplitudes/null
polygonal Wilson loops in planar\(\mathcal {N}\)= 4 Super-Yang-Mills theory. It allows one to …

Universal structure of subleading infrared poles in gauge theory amplitudes

LJ Dixon, L Magnea, G Sterman - Journal of High Energy Physics, 2008 - iopscience.iop.org
We study the origin of subleading soft and collinear poles of form factors and amplitudes in
dimensionally-regulated massless gauge theories. In the case of form factors of fundamental …
