Abstract
We obtain concise analytic formulae for Wilson loops computed on special n-point polygonal contours through two-loops in weakly coupled \( \mathcal{N} = 4 \) supersymmetric gauge theory. The contours we consider can be embedded into a (1 + 1)-dimensional subspace of the 4-dimensional gauge theory, corresponding to the boundary of the AdS 3 on the string theory side. Our analytic results hold for any number of edges, thus generalising to arbitrary n the recently derived expressions for 2-dimensional octagons. These polygonal Wilson loops have been conjectured to be equivalent to MHV scattering amplitudes in planar \( \mathcal{N} = 4 \) SYM.
