Supersymmetric Wilson loops in two dimensions and duality
Supersymmetric Wilson loops in two dimensions and duality
We classify bosonic $\mathcal{N}=(2,2)$ supersymmetric Wilson loops on arbitrary backgrounds with vectorlike R-symmetry. These can be defined on any smooth contour and come in two forms which are universal across all backgrounds. We show that these Wilson loops, due to their cohomological properties, are all invariant under smooth deformations of …
