Title: T$$ \overline{T} $$ deformation in SCFTs and integrable supersymmetric theories

Abstract

We calculate the \( \mathcal{S} \)-multiplets for two-dimensional Euclidean \( \mathcal{N} \) = (0, 2) and \( \mathcal{N} \) = (2, 2) superconformal field theories under the T\( \overline{T} \) deformation at leading order of perturbation theory in the deformation coupling. Then, from these \( \mathcal{N} \) = (0, 2) deformed multiplets, we calculate two- and three-point correlators. We show the \( \mathcal{N} \) = (0, 2) chiral ring’s elements do not flow under the T\( \overline{T} \) deformation. Specializing to integrable supersymmetric seed theories, such as \( \mathcal{N} \) = (2, 2) Landau-Ginzburg models, we use the thermodynamic Bethe ansatz to study the S-matrices and ground state energies. From both an S-matrix perspective and Melzer’s folding prescription, we show that the deformed ground state energy obeys the inviscid Burgers’ equation. Finally, we show that several indices independent of D-term perturbations including the Witten index, Cecotti-Fendley-Intriligator-Vafa index and elliptic genus do not flow under the T\( \overline{T} \) deformation.
