Dual superconformal symmetry of scattering amplitudes in N=4 super-Yang-Mills theory

- J. Drummond, J. Henn, G. Korchemsky, E. Sokatchev
- Physics
- 7 July 2008

We argue that all scattering amplitudes in the maximally supersymmetric N=4 super-Yang–Mills theory possess a new, dual superconformal symmetry which extends the previously discovered dual conformal… Expand

Conformal properties of four-gluon planar amplitudes and Wilson loops

- J. Drummond, G. Korchemsky, E. Sokatchev
- Physics
- 2 July 2007

We present further evidence for a dual conformal symmetry in the four-gluon planar scattering amplitude in N=4 SYM. We show that all the momentum integrals appearing in the perturbative on-shell… Expand

Review of AdS/CFT Integrability: An Overview

- N. Beisert, C. Ahn, +23 authors K. Zoubos
- Physics
- 17 December 2010

This is the introductory chapter of a review collection on integrability in the context of the AdS/CFT correspondence. In the collection, we present an overview of the achievements and the status of… Expand

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

- J. Drummond, J. Henn, G. Korchemsky, E. Sokatchev
- Physics
- 11 February 2010

Planar gluon amplitudes in N=4N=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 use of the… Expand

Renormalization of the Wilson loops beyond the leading order

- G. Korchemsky, A. Radyushkin
- Physics
- 1987

Abstract We study the renormalization properties of the Wilson loops containing cusp singularities. In particular, we calculate the two-loop contribution to the cusp anomalous dimension Γ cusp ( γ ,… Expand

From correlation functions to Wilson loops

- L. Alday, B. Eden, G. Korchemsky, J. Maldacena, E. Sokatchev
- Physics
- 19 July 2010

We start with an n−point correlation function in a conformal gauge theory. We show that a special limit produces a polygonal Wilson loop with n sides. The limit takes the n points towards the… Expand

Logarithmic scaling in gauge/string correspondence

- A. Belitsky, A. Gorsky, G. Korchemsky
- Physics
- 16 January 2006

Abstract We study anomalous dimensions of (super)conformal Wilson operators at weak and strong coupling making use of the integrability symmetry on both sides of the gauge/string correspondence and… Expand

Hexagon Wilson loop = six-gluon MHV amplitude

- J. Drummond, J. Henn, G. Korchemsky, E. Sokatchev
- Physics
- 1 July 2009

Abstract 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 SYM… Expand

On planar gluon amplitudes/Wilson loops duality

- J. Drummond, J. Henn, G. Korchemsky, E. Sokatchev
- Physics
- 14 September 2007

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-like segments defined… Expand

Gauge/string duality for QCD conformal operators

- A. Belitsky, A. Gorsky, G. Korchemsky
- Physics
- 3 April 2003

Abstract Renormalization group evolution of QCD composite light-cone operators, built from two and more quark and gluon fields, is responsible for the logarithmic scaling violations in diverse… Expand
