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 …

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 …

Conformal Ward identities for Wilson loops and a test of the duality with gluon amplitudes

JM Drummond, J Henn, GP Korchemsky, E Sokatchev - Nuclear Physics B, 2010 - Elsevier
Planar gluon amplitudes in N= 4 SYM are remarkably similar to expectation values of Wilson
loops made of light-like segments. We argue that the latter can be determined by making …

Two-loop six-gluon maximally helicity violating amplitude in maximally supersymmetric<? format?> Yang-Mills theory

Z Bern, LJ Dixon, DA Kosower, R Roiban… - Physical Review D …, 2008 - APS
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 …

[HTML][HTML] On planar gluon amplitudes/Wilson loops duality

JM Drummond, J Henn, GP Korchemsky, E Sokatchev - Nuclear physics B, 2008 - Elsevier
There is growing evidence that on-shell gluon scattering amplitudes in planar N= 4 SYM
theory are equivalent to Wilson loops evaluated over contours consisting of straight, light …

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 …

Dual superconformal symmetry from superstring integrability

N Beisert, R Ricci, AA Tseytlin, M Wolf - Physical Review D—Particles, Fields …, 2008 - APS
We discuss 2 d duality transformations in the classical AdS 5× S 5 superstring and their
effect on the integrable structure. T-duality along four directions in the Poincaré …

The all loop AdS4/CFT3 Bethe ansatz

N Gromov, P Vieira - Journal of High Energy Physics, 2009 - iopscience.iop.org
We propose a set of Bethe equations yielding the full asymptotic spectrum of the AdS 4/CFT
3 duality proposed in arXiv: 0806.1218 to all orders in the t'Hooft coupling. These equations …

Scattering into the fifth dimension of = 4 super Yang-Mills

LF Alday, J Henn, J Plefka, T Schuster - Journal of High Energy Physics, 2010 - Springer
We study an alternative to dimensional regularisation of planar scattering amplitudes
in\(\mathcal {N}\)= 4 super Yang-Mills theory by going to the Coulomb phase of the theory …

Supersymmetric Wilson loops on S3

N Drukker, S Giombi, R Ricci… - Journal of High Energy …, 2008 - iopscience.iop.org
This paper studies in great detail a family of supersymmetric Wilson loop operators in Script
N= 4 supersymmetric Yang-Mills theory we have recently found. For a generic curve on an S …
