"Massive" Conformal Field Theories and application to Nambu-Goto string

Abstract

I describe the recent progress in understanding diffeomorphism invariant two-dimensional theories with dimensionful parameters which have nevertheless traceless improved energy-momentum tensor and turn out to be conformal invariant. An example is the Liouville theory with the additional four-derivative terms arising from the Nambu-Goto string and telling apart the Nambu-Goto and Polyakov strings. Its exact solution in embedding dimension d=4 is consistent in contrast to the Polyakov string and described by the (4,3) unitary minimal model. Talk at Irina Aref'eva Conference "Perspective Directions in Quantum Field Theory and Superstrings", Moscow 12-17 October 2026.
