Simplified Models for Vector Boson Scattering at ILC and CLIC
  Quasi-elastic scattering of the vector bosons W and Z is a sensitive probe of the details of electroweak symmetry breaking, and a key process at future lepton colliders. We discuss the limitations of a model-independent effective-theory approach and describe the extension to a class of Simplified Models that is applicable to all energies in a quantitative way, and enables realistic Monte-Carlo simulations. The framework has been implemented in the Monte-Carlo event generator WHIZARD.
