SUMMARY:Oluf Engelund\, Uppsala - Generalized Unitarity for Integrable 2D S
  Matrices
DESCRIPTION:Generalized unitarity is a powerful method for doing perturbati
 ve calculations. We will discuss how to apply it to worldsheet S-matrices 
 for the Green-Schwarz string in curved space. The studied theories are bel
 ieved to be integrable to all orders in perturbation theory and symmetries
  have been used to determine exact S-matrices up to an overall dressing ph
 ase. Generalized unitarity can provide a simple way to check the proposed 
 S-matrices perturbatively and to find dressing phases. As an example we wi
 ll focus on $\\eta$-deformed $AdS_5 \\times S^5$
