Symmetric Wilson Loops beyond leading order

We study the circular Wilson loop in the symmetric representation of U(N) in $\mathcal{N}=4$ super-Yang-Mills (SYM). In the large N limit, we computed the exponentially-suppressed corrections for strong coupling, which suggests non-perturbative physics in the dual holographic theory. We also computed the next-to-leading order term in 1/N, and the result matches with the exact result from the k-fundamental representation.
