An exact formula for the radiation of a moving quark in $\mathcal{N} = 4$ super Yang Mills

- D. Correa, J. Henn, J. Maldacena, A. Sever
- Physics
- 20 February 2012

A bstractWe derive an exact formula for the cusp anomalous dimension at small angles. This is done by relating the latter to the computation of certain 1/8 BPS Wilson loops which was performed by… Expand

An operator product expansion for polygonal null Wilson loops

- L. Alday, D. Gaiotto, J. Maldacena, A. Sever, P. Vieira
- Physics
- 14 June 2010

We consider polygonal Wilson loops with null edges in conformal gauge theories. We derive an OPE-like expansion when several successive lines of the polygon are becoming aligned. The limit… Expand

Tailoring three-point functions and integrability

- J. Escobedo, N. Gromov, A. Sever, P. Vieira
- Physics
- 11 December 2010

We use integrability techniques to compute structure constants in $ \mathcal{N} = 4 $ SYM to leading order at weak coupling and to leading order in the planar expansion. Three closed spin chains,… Expand

The cusp anomalous dimension at three loops and beyond

- D. Correa, J. Henn, J. Maldacena, A. Sever
- Physics
- 5 March 2012

We derive an analytic formula at three loops for the cusp anomalous dimension Γcusp(ϕ) in $ \mathcal{N} = {4} $ super Yang-Mills. This is done by exploiting the relation of the latter to the Regge… Expand

Spacetime and flux tube S-matrices at finite coupling for N=4 supersymmetric Yang-Mills theory.

We propose a nonperturbative formulation of planar scattering amplitudes in N=4 supersymmetric Yang-Mills theory, or, equivalently, polygonal Wilson loops. The construction is based on the operator… Expand

The quark anti-quark potential and the cusp anomalous dimension from a TBA equation

- D. Correa, J. Maldacena, A. Sever
- Physics
- 8 March 2012

A bstractWe derive a set of integral equations of the TBA type for the generalized cusp anomalous dimension, or the quark antiquark potential on the three sphere, as a function of the angles. We do… Expand

Space-time S-matrix and flux tube S-matrix II. Extracting and matching data

A bstractWe 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 compute a precise… Expand

Space-time S-matrix and flux-tube S-matrix III. The two-particle contributions

A bstractWe consider light-like Wilson loops with hexagonal geometry in the planar limit of N$$ \mathcal{N} $$ = 4 Super-Yang-Mills theory. Within the Operator-Product-Expansion framework these loops… Expand

`Double-trace' deformations, boundary conditions and spacetime singularities

- M. Berkooz, A. Sever, Assaf Shomer
- Physics
- 31 December 2001

Double-trace deformations of the AdS/CFT duality result in a new perturbation expansion for string theory, based on a non-local worldsheet. We discuss some aspects of the deformation in the low… Expand

Pulling the straps of polygons

- D. Gaiotto, J. Maldacena, A. Sever, P. Vieira
- Physics
- 1 February 2011

A bstractUsing the Operator Product Expansion for Wilson loops we derive a simple formula giving the discontinuities of the two loop result in terms of the one loop answer. We also argue that the… Expand
