Vector Boson Scattering is central to our understanding of the Electroweak Symmetry Breaking Mechanism. Corrections to the Standard Model are conventionally studied in Standard Model Effective Field Theory (SMEFT). However, SMEFT can be cast in the form of the more general Higgs Effective Field Theory (HEFT). We expose the SMEFT-induced correlations on the coefficients of HEFT that, if found...
Studying the polarization of weak bosons provides crucial information to better understand the electroweak-symmetry-breaking mechanism that is realized in nature. We will report on the status of Standard-Model calculations of polarized di-boson production in the VBF channel at the LHC, with a focus on vector-boson-scattering and VBF Higgs-boson production. We will show a number of...
Vector Boson Fusion (VBF) is a purely electroweak process and a fundamental tool to test the electroweak sector of the standard model (SM). Leptonic decay modes of the vector bosons are used to measure SM processes and search for physics beyond the SM, since they feature a clean signature and hence, a lower level of background.
We present a parton-level study in two VBF channels at the Large...
