Abstract
We study scalar excitations of high spin operators in \( \mathcal{N} = 4 \) super Yang-Mills theory, which are dual to solitons propagating on a long folded string in AdS 3 × S 1. In the spin chain description of the gauge theory, these are associated to holes in the magnon distribution in the \( \mathfrak{s}\mathfrak{l}\left( {2,\mathbb{R}} \right) \) sector. We compute the all-loop hole S-matrix from the asymptotic Bethe ansatz, and expand in leading orders at weak and strong coupling. The worldsheet S-matrix of solitonic excitations on the GKP string is calculated using semiclassical quantization. We find an exact agreement between the gauge theory and string theory results.
