This article introduces a deformation of two-dimensional quantum field theories generated by a nonanalytic operator called Root-T(T) over bar. The deformation is closely related to conformal field theory and ModMax theory.
In this Letter, we introduce a one-parameter deformation of two-dimensional quantum field theories generated by a nonanalytic operator that we call Root-T (T) over bar. For a conformal field theory, the operator coincides with the square root of the T (T) over bar operator. More generally, the operator is defined so that classically it is marginal and generates a flow that commutes with the T (T) over bar flow. Intriguingly, the Root-T (T) over bar flow is closely related to the ModMax theory recently constructed by Bandos, Lechner, Sorokin, and Townsend.
