Journal ArticleDOI
Quantum wrapped giant magnon
TL;DR: In this paper, the authors compute the leading exponential correction to the quantum energy of the fundamental excitation of the light-cone gauged string in AdS5×S^5, which is the giant magnon solution.
Journal ArticleDOI
Bootstrapping null polygon Wilson loops
TL;DR: In this paper, the two loop expressions for polygonal Wilson loops were derived by starting from the one loop expressions and applying an operator product expansion, and the result was in agreement with previous computations.
Journal ArticleDOI
Space-time S-matrix and Flux-tube S-matrix III. The two-particle contributions
TL;DR: In this article, the authors considered light-like Wilson loops with hexagonal geometry in the planar limit of N=4 Super-Yang-Mills theory and derived the twist-2 corrections to the expansion of the dual 6-gluons MHV amplitude in the nearcollinear limit at finite coupling.
Journal ArticleDOI
OPE for all helicity amplitudes
TL;DR: In this article, a simple map between helicity congurations and so-called charged pentagon transitions is constructed, which can be bootstrapped from the integrable dynamics of the color ux tube.
Journal ArticleDOI
Gluing hexagons at three loops
TL;DR: In this paper, the authors performed extensive three-loop tests of the hexagon bootstrap approach for structure constants in planar N = 4 SYM theory and found that the first type of correction coincides exactly with the leading wrapping correction for the spectrum.
