Abstract
A bstract : Motivated by earlier approaches, we develop a worldsheet framework for computing correlation functions in the single trace TT̅ T T ¯ -deformed tensionless AdS ₃ /CFT ₂ duality. By describing the deformed bulk theory as a Berkovits-Vafa 𝒩 N = 4 topological string, we obtain a consistent definition of physical states and correlation functions, yielding a tractable setup for testing aspects of holography beyond AdS/CFT. We construct deformed physical vertex operators and compute their tree-level two-point functions exactly. We discuss the relation of our results to previous proposals for TT̅ T T ¯ -deformed two-point functions obtained from alternative worldsheet approaches, JT gravity, and perturbative field theory computations.
