Description
After Run 2 of the Large Hadron Collider, the Standard Model (SM)
of Particle Physics passes all tests against data from collider
experiments without any significant exception. In particular,
the Higgs boson discovered at the LHC in 2012 looks rather SM-like.
With the absence of spectacular signs of new physics, this means
that traces of physics beyond the SM have to be sought in small
and subtle effects in the data, so that precision in theory and
experiment might be the road to new discoveries. With increasing
energy and luminosity at the LHC, the analysis of rare electroweak
processes such as the scattering of electroweak vector-boson
scattering becomes feasible and more and more important. This
process class provides deeper insight into the self-interactions of
electroweak gauge bosons as well as a window to electroweak
symmetry breaking that is complementary to direct analyses of the
Higgs boson. The talk reviews the basic motivation for
investigating vector-boson scattering and highlights recent
developments in the theoretical description of this process class
which is rather complex with four leptons and two jets as
experimental signature.
