  We consider SUSY sine-Gordon theory in the framework of perturbed conformal
field theory. Using an argument from Zamolodchikov, we obtain the vacuum
structure and the kink adjacency diagram of the theory, which is cross-checked
against the exact S matrix prediction, first-order perturbed conformal field
theory (PCFT), the NLIE method and truncated conformal space approach. We
provide evidence for consistency between the usual Lagrangian description and
PCFT on the one hand, and between PCFT, NLIE and a massgap formula conjectured
by Baseilhac and Fateev, on the other. In addition, we extend the NLIE
description to all the vacua of the theory.
