Constraining integrable AdS/CFT with factorized scattering

摘要
En 中文
We consider (warped) AdS string backgrounds which allow for a GKP spinning string/null cusp solution. Integrability implies that the worldsheet S-matrix should factorize, which in turn constrains the form of the warp factor as a function of the coordinates of the internal space. This constraint is argued to rule out integrability for all supersymmetric AdS(7) and AdS(6) backgrounds as well as AdS(5) Gaiotto-Maldacena backgrounds and a few highly supersymmetric AdS(4) and AdS(3) backgrounds.
