摘要

We propose a double-scaling limit of β-deformed ABJM theory in three-dimensional N \( \mathcal{N} \) = 2 superspace, and a non-local deformation thereof. Due to the regular appearance of the theory’s Feynman supergraphs, we refer to this superconformal and integrable theory as the superfishnet theory. We use techniques inspired by the integrability of bi-scalar fishnet theory and adapted to superspace to calculate the zero-mode-fixed thermodynamic free energy, the corresponding critical coupling, and the exact all-loop scaling dimensions of various operators. Furthermore, we confirm the results of the supersymmetric dynamical fishnet theory by applying our methods to four-dimensional N \( \mathcal{N} \) = 1 superspace.
