Description
Vector boson scattering at the LHC has recently been discovered in the process $p p \to \mu^+\nu_\mu e^+\nu_e$, the so-called same-sign WW channel. This opens a new window for studying the nature of electroweak symmetry breaking and the role of the Higgs boson. Precision predictions for this process are thus of great importance. In this talk, the electroweak corrections at next-to-leading order for the same-sign WW channel will be presented. Reaching $-16\%$ at the level of the inclusive cross section, they turn out to be surprisingly large and of similar size as the corresponding NLO QCD corrections. At the level of differential distributions, they are even more enhanced in the high-energy regime. We will present predictions that combine both NLO EW and QCD corrections, and will review their different behaviour and origin. A phenomenological analysis with realistic acceptance cuts is shown.
