Ladder exponentiation for generic large symmetric representation Wilson loops
(Springer, 2015-11)
A recent proposal was made for a large representation rank limit for which the expectation values of N=4 super Yang-Mills Wilson loops are given by the exponential of the 1-loop result. We verify the validity of this ...
The cusp anomalous dimension at three loops and beyond
(Springer, 2012-05)
We derive an analytic formula at three loops for the cusp anomalous dimension Γ cusp(φ) in N = 4 super Yang-Mills. This is done by exploiting the relation of the latter to the Regge limit of massive amplitudes. We comment ...
Dilogarithm ladders from Wilson loops
(Springer, 2015-02)
We consider a light-like Wilson loop in N = 4 SYM evaluated on a regular n-polygon contour. Sending the number of edges to infinity the polygon approximates a circle and the expectation value of the light-like WL is expected ...
D5-brane baoundary reflection factors
(Springer Verlag Berlín, 2013-05)
We compute the strong coupling limit of the boundary reflection factor for excitations on open strings attached to various kinds of D5-branes that probe AdS5 x S5. We study the crossing equation, which constrains the ...
Dyson equations for correlators of Wilson loops
(Springer, 2018-12)
By considering a Gaussian truncation of N = 4 super Yang-Mills, we derive a set of Dyson equations that account for the ladder diagram contribution to connected correlators of circular Wilson loops. We consider different ...
Functional determinants of radial operators in AdS 2
(Springer Verlag, 2018-06)
We study the zeta-function regularization of functional determinants of Laplace and Dirac-type operators in two-dimensional Euclidean AdS2 space. More specifically, we consider the ratio of determinants between an operator ...
Light-like Wilson loops in ABJM and maximal transcendentality
(Springer Verlag Berlín, 2013-08)
We revisit the computation of the two-loop light-like tetragonal Wilson loop for three dimensional pure Chern-Simons and N=6 Chern-Simons-matter theory, within dimensional regularization with dimensional reduction scheme. ...
Semiclassical partition function for strings dual to Wilson loops with small cusps in ABJM
(Springer, 2015-03)
Abstract: We compute the 1-loop partition function for strings in AdS4 × ℂℙ3, whose worldsheets end along a line with small cusp angles in the boundary of AdS. We obtain these 1-loop results in terms of the vacuum energy ...
Beyond AdS2/dCFT1: insertions in two Wilson loops
(Springer Science and Business Media Deutschland GmbH, 2023-10)
We consider two-point correlators of local operator insertions in a system of two Wilson-Maldacena loops in N = 4 supersymmetric Yang-Mills theory on both sides of the AdS/CFT correspondence. On the holographic side the ...

(2023)
Abstract: We consider two-point correlators of local operator insertions in a system of two Wilson-Maldacena loops in N = 4 supersymmetric Yang-Mills theory on both sides of the AdS/CFT correspondence. On the holographic ...
