Exact resonance A-D-E S-matrices and their renormalization group trajectories

Abstract

We introduce the A-D-E resonance factorized models as an appropriate analytical continuation of the Toda S-matrices to the complex values of their coupling constant. An investigation of the associated Casimir energy, via the thermodynamic Bethe ansatz, reveals a rich pattern of renormalization group trajectories interpolating between the central charges of the $G_1\otimes G_k/G_{k+1}$ GKO coset models. We have also constructed the simplest resonance factorized model satisfying the ``${\varphi }^3$''-property. From this resonance scattering, we predict new flows in non-unitary minimal models.
