Two - Loop Polygon Wilson Loops in N = 4 SYM

We compute for the first time the two-loop corrections to arbitrary n-gon lightlike Wilson loops in N = 4 supersymmetric Yang-Mills theory, using efficient numerical methods. The calculation is motivated by the remarkable agreement between the finite part of planar six-point MHV amplitudes and hexagon Wilson loops which has been observed at two loops. At n = 6 we confirm that the ABDK/BDS ansat...

From Polygon Wilson Loops to Spin Chains and Back

Null Polygon Wilson Loops in N = 4 SYM can be computed using the Operator Product Expansion in terms of a transition amplitude on top of a color Flux tube. That picture is valid at any value of the ’t Hooft coupling and is studied here in the planar limit. So far it has been efficiently used at weak coupling in cases where only a single particle is flowing. At any finite value of the coupling h...

Null Wilson loops with a self-crossing and the Wilson loop/amplitude conjecture

The present study illuminates the relation between null cusped Wilson loops and their corresponding amplitudes. We find that, compared to the case with no selfcrossing, the one loop expectation value of a self-intersecting Wilson loop develops an additional 1/ǫ singularity associated to the intersection. Interestingly, the same 1/ǫ pole exists in the finite part of the one loop amplitude, appea...

Bootstrapping and Askey-wilson Polynomials

Abstract. The mixed moments for the Askey-Wilson polynomials are found using a bootstrapping method and connection coe cients. A similar bootstrapping idea on generating functions gives a new Askey-Wilson generating function. Modified generating functions of orthogonal polynomials are shown to generate polynomials satisfying recurrences of known degree greater than three. An important special c...

Holographic Wilson Loops

We show that all half-BPS Wilson loop operators in N = 4 SYM – which are labeled by Young tableaus – have a gravitational dual description in terms of D5-branes or alternatively in terms of D3-branes in AdS5×S. We prove that the insertion of a half-BPS Wilson loop operator in the N = 4 SYM path integral is achieved by integrating out the degrees of freedom on a configuration of bulk D5-branes o...
