RG Flows: S-Matrix Bootstraps and Non-invertible Symmetries
ABSTRACT
By obtaining complete solutions of the S-matrix bootstrap equations for massless particle scattering in (1+1) dimensions, I demonstrate the emergence of new renormalization group (RG) flows connecting ultraviolet (UV) and infrared (IR) non-unitary conformal field theories (CFTs). These flows are also confirmed by the non-invertible symmetries of Verlinde defect lines in coset non-unitary CFTs.
