Vector Boson Scattering: status and prospects
2019 September 19
The scattering of vector bosons (VBS) happens at the Large Hadron Collider when, in a proton collision, two vector bosons radiate from the interacting quarks and scatter. The VBS process is of great interest because of its intimate relationship with the foundations of the Standard Model of the fundamental interactions, since its unitarity is granted by the EW symmetry breaking. Therefore studying the VBS gives access to the EWSB in an orthogonal way with respect to the Higgs boson physics. Despite being among the rarest processes studied so far, the first results have already been published by the ATLAS and CMS Collaborations, triggering the experimental and theory communities in adding more final states on the measurement side, and pursuing more precision on the theory one. On the long term, the high-luminosity LHC will deliver a dataset of unprecendented size, that will allow to fully exploit the VBS topology, which is nowadays still fully dominated by the statistical uncertainties.
