We calculate Wilson loops in lowest order of perturbation theory for triangular contours whose edges are circular arcs. Based on a suitable disentanglement of the relations between metrical and conformal parameters of the contours, the result fits perfectly in the structure predicted by the anomalous conformal Ward identity. The conformal remainder function depends in the generic 4D case on three cusp and on three torsion angles. The restrictions on these angles imposed by the closing of the… 

Remarks on conformal invariants for piecewise smooth curves and Wilson loops

This short note is some obvious mathematical addendum to our papers on Wilson loops on polygon-like contours with circular edges [1, 2]. Using the technique of osculating spheres and circles we

We derive the anomalous conformal Ward identities for N $$ \mathcal{N} $$ = 4 SYM Wilson loops on polygon-like contours with edges formed by circular arcs. With a suitable choice of parameterisation

Large-size expansion for triangular Wilson loops in confining gauge theories

The asymptotic behavior of Wilson loops in the large-size limit ( L → ∞ ) in confining gauge theories with area law is controlled by effective string theory (EST). The L − 2 term of the large-size

Conformal geometry of null hexagons for Wilson loops and scattering amplitudes

The cross-ratios do not uniquely fix the class of conformally equivalent configurations of null polygons. In view of applications to Wilson loops and scattering amplitudes we characterise all

On a new type of divergence for spiky Wilson loops and related entanglement entropies

A bstractWe study the divergences of Wilson loops for a contour with a cusp of zero opening angle, combined with a nonzero discontinuity of its curvature. The analysis is performed in lowest order,

Supersymmetric Wilson loops on S**3.

This paper studies in great detail a family of supersymmetric Wilson loop operators in = 4 supersymmetric Yang-Mills theory we have recently found. For a generic curve on an S3 in space-time the

Minimal area surfaces in AdSn+1 and Wilson loops

A bstractThe AdS/CFT correspondence relates the expectation value of Wilson loops in N$$ \mathcal{N} $$ = 4 SYM to the area of minimal surfaces in AdS5. In this paper we consider minimal area

Quantum spectral curve and structure constants in N=4$$ \mathcal{N}=4 $$ SYM: cusps in the ladder limit

A bstractWe find a massive simplification in the non-perturbative expression for the structure constant of Wilson lines with 3 cusps when expressed in terms of the key Quantum Spectral Curve

Gluon scattering amplitudes at strong coupling

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