Dual superconformal symmetry of scattering amplitudes in N=4 super-Yang-Mills theory
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 conformalExpand
Conformal properties of four-gluon planar amplitudes and Wilson loops
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-shellExpand
Review of AdS/CFT Integrability: An Overview
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 ofExpand
Conformal Ward identities for Wilson loops and a test of the duality with gluon amplitudes
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 theExpand
Renormalization of the Wilson loops beyond the leading order
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
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 theExpand
Logarithmic scaling in gauge/string correspondence
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 andExpand
Hexagon Wilson loop = six-gluon MHV amplitude
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 SYMExpand
On planar gluon amplitudes/Wilson loops duality
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 definedExpand
Gauge/string duality for QCD conformal operators
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 diverseExpand
