Multi-boson Production in Weak Boson Fusion

Abstract: The production of multiple gauge bosons via weak boson fusion is an important process at the LHC. It is relevant as a background process appearing in many searches and measurements, but also serves as a signal process when studying new-physics contributions to triple and in particular quartic gauge boson vertices. We first review the theoretical status of multi-boson production in weak boson fusion and present the current state of the art. In the second part, the impact of anomalous gauge couplings on this class of processes is discussed.
