Aiming at nonexperts, the key mechanisms of higher-spin extensions of ordinary gravities in
four dimensions and higher are explained. An overview of various no-go theorems for low …

We describe how to compute planar gluon scattering amplitudes at strong coupling in Script
N= 4 super Yang Mills by using the gauge/string duality. The computation boils down to …

We consider high spin operators. We give a general argument for the logarithmic scaling of
their anomalous dimensions which is based on the symmetries of the problem. By an …

Abstract Studies of super Yang–Mills operators with large R-charge have shown that, in the
planar limit, the problem of computing their dimensions can be viewed as a certain spin …

We analyze in detail the relation between an exactly marginal deformation of Script N= 4
SYM—the Leigh-Strassler or``β-deformation''—and its string theory dual (recently …

In order to analyze finite-size effects for the gauge-fixed string sigma model on AdS5× S5,
we construct one-soliton solutions carrying finite angular momentum J. In the infinite J limit …

We consider minimal surfaces in three dimensional anti-de-Sitter space that end at the AdS
boundary on a polygon given by a sequence of null segments. The problem can be reduced …

A bstract Using integrability, we construct (to leading order in perturbation theory) the explicit
form of twist-three light-ray operators in planar\(\mathcal {N}\)= 4 SYM. This construction …

Recently, classical solutions for strings moving in AdS 5× S 5 have played an important role
in understanding the AdS/CFT correspondence. A large set of them were shown to follow …

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 …
