Vector Boson Scattering (VBS) is one of the rarest processes measured at the LHC, where two vector bosons radiated from incoming quarks scatter off each other. These measurements provide a unique experimental window into the mechanism of Electroweak Symmetry Breaking (EWSB), complementary to direct Higgs boson measurements. Within the Standard Model (SM), Higgs boson contributions are essential to restore unitarity in the scattering amplitude of longitudinally polarised weak bosons at TeV-scale energies, and any deviation would signal physics beyond the Standard Model (BSM). This talk gives an overview of VBS measurements at the LHC, covering both tests of SM predictions and searches for BSM physics.
