Yangian symmetry of light-like Wilson loops
Yangian symmetry of light-like Wilson loops
We show that a certain class of light-like Wilson loops exhibits a Yangian symmetry at one loop, or equivalently, in an Abelian theory. The Wilson loops we discuss are equivalent to one-loop MHV amplitudes in $ \mathcal{N} = 4 $ super Yang-Mills theory in a certain kinematical regime. The fact …
