Abstract
The standard unitarity-cut method is applied to several massive two-dimensional models, including the world-sheet AdS superstring, to compute scattering S-matrices at one loop from tree level amplitudes. Evidence is found for the cut-constructibility of supersymmetric integrable models, while for models without supersymmetry (but integrable) the missing rational terms can be interpreted as a shift in the coupling.
