Studying electroweak sector of the Standard Model with the ATLAS detector

Description
Studies of electroweak gauge boson pairs at the LHC examine
the gauge structure of the Standard Model, with experimental
measurements sensitive to theoretical predictions beyond leading order
calculations. Inclusive production of gauge boson pairs is used to
study triple gauge boson self-couplings and to search for new physics
phenomena. Production of boson pairs via Vector Boson Scattering
processes involves quartic gauge couplings and is sensitive to precise
cancellations among various perturbative contributions, including
those from the Higgs boson. This presentation will discuss most recent
studies of electroweak boson pairs by the ATLAS collaboration,
including observation of the electroweak production of same sign W
boson pairs.
