Correlators in $T\bar{T}$ and Root-$T\bar{T}$ Deformed CFTs
Abstract
Quasi-primary correlators in two-dimensional conformal field theories deformed simultaneously by and root- are studied. A path-integral formulation motivated by the geometric realization of the combined deformation is used to develop a geometric framework for evaluating the deformed correlators. Within this framework, the two-point function is obtained to all orders in the coupling and to leading order in the root- coupling, while the leading correction to the three-point function is computed. It is further shown that the deformed two-point correlator admits a kernel representation as a weighted average of undeformed CFT correlators over conformal dimensions. This representation is derived explicitly for both the pure deformation and the combined flow. In this way, the mixed /root- deformation is incorporated into the geometric description of irrelevant deformations, and the structure of local correlators beyond the pure case is characterized more explicitly.
