The convergence of strongly relevant perturbations of d = 2 conformal field theories

Abstract

Off-critical perturbations of two-dimensional rational conformal field theories given by scalar primary operators with scaling dimensions smaller than (1/2, 1/2) are considered. The Gell-Mann-Low expansion is shown to converge in finite volume.
