Tu model unitarization in VBS — •Heiko Schäfer-Siebert — KIT, ITP
Vector Boson Scattering (VBS) at the LHC provides a window on possible effects of physics beyond the SM in electroweak symmetry breaking, which can be described in an effective Lagrangian framework. The use of higher dimension operators leads to a UV incomplete theory, however, that breaks unitarity at high energies. In order to handle this unphysical behavior and to study VBS phenomenologically, the Tu model was developed as a numerical unitarization scheme for off-shell weak boson scattering. I will present the Tu unitarization procedure and its application to dimension eight operators that influence the VV → VV scattering within the full VBS VVjj production processes. The necessary adaptations when going from same sign WW to WZjj and Wγ jj production are discussed, including the influence of Higgs boson states on the unitarization results.
