Integrable S matrix, mirror TBA and spectrum for the stringy WZW model
Andrea Dei, Alessandro Sfondrini
We compute the tree-level bosonic S matrix in light-cone gauge for superstrings on pure-NSNS . We show that it is pr…
On deformations and supersymmetry
Marco Baggio, Alessandro Sfondrini, Gabriele Tartaglino-Mazzucchelli +1
We investigate the "" deformations of two-dimensional supersymmetric quantum field theories. More precisely, we show that, by using the conservation equations for the sup…
Positivity of hexagon perturbation theory
Burkhard Eden, Yunfeng Jiang, Marius de Leeuw +3
The hexagon-form-factor program was proposed as a way to compute three- and higher-point correlation functions in super-symmetric Yang-Mills theory and in the dual…
Integrable spin chain for stringy Wess-Zumino-Witten models
Andrea Dei, Alessandro Sfondrini
Building on arXiv:1804.01998 we investigate the integrable structure of the Wess-Zumino-Witten (WZW) model describing closed strings on . Using the recen…
The plane-wave limit of
Andrea Dei, Matthias R. Gaberdiel, Alessandro Sfondrini
The plane-wave limit of is analysed for generic null-geodesics that are not necessarily BPS. For the case of pure N…
Strings on NS-NS Backgrounds as Integrable Deformations
Marco Baggio, Alessandro Sfondrini
We consider the worldsheet S matrix of superstrings on an AdS3xS3xT4 NS-NS background in uniform light-cone gauge. We argue that scattering is given by a CDD factor that is non-tri…
