      Vector Boson Scattering at the LHC - Precision, Polarization and New Physics Searches 1h 30m

      Abstract:

      The scattering of electroweak vector bosons (VBS) is at the heart of electroweak symmetry breaking: it demonstrates the unitarization by the Higgs exchange, which is a subtle cancellation of quadratic energy rise.
      This, together with the fact, that VBS covers the multi-TeV energy range make it an ideal tool to search for new physics. In this talk, I will discuss the status of the SM precision calculation, also for polarized VBS. Three types of new physics signal modelling will be
      presented: SM effective field theories (SMEFT), simplified models, and specific new physics models important for VBS. Pros and cons of these modellings will be discussed.
