Diboson Physics in ATLAS

At the LHC, the diboson states (W$^+$,W$^-$) (Z,Z), (W$^\pm$,Z), (W$^\pm$,$\gamma$) and (Z,$\gamma$) arise primarly through quark-quark interactions and to a lesser extent from gluon-gluon fusion. Diboson production cross sections are determined, in part, by the Standard Model triple-gauge-boson couplings and the strength of anomalous triple gauge couplings. We report on the studies of expected ATLAS measurements of diboson production cross sections with leptonic and photon final states. Such potential measurements can probe anomolous triple gauge boson couplings and are sensitive to physics beyond the Standard Model.
