Unitarity methods for scattering in two dimensions

Forini, V. ORCID: 0000-0001-9726-1423, Bianchi, L. & Hoare, B. (2015). Unitarity methods for scattering in two dimensions. Springer Proceedings in Physics, 170, pp. 169-177. doi: 10.1007/978-3-319-20046-0_20


The standard unitarity-cut method is applied to several massive two-dimensional models, including the world-sheet AdS 5×S5 superstring, to compute 2→2 scattering S-matrices at one loop from tree level amplitudes. Evidence is found for the cut-constructibility of supersymmetric models, while for models without supersymmetry (but integrable) the missing rational terms can be interpreted as a shift in the coupling.
