Master Symmetry for Holographic Wilson Loops (1606.04104v3)
Published 13 Jun 2016 in hep-th, math-ph, math.MP, and nlin.SI
Abstract: We identify the symmetry underlying the recently observed spectral-parameter transformations of holographic Wilson loops alias minimal surfaces in AdS/CFT. The generator of this nonlocal symmetry is shown to furnish a raising operator on the classical Yangian-type charges of symmetric coset models. We explicitly demonstrate how this master symmetry acts on strong-coupling Wilson loops and indicate a possible extension to arbitrary coupling.
