Description

Diboson production cross sections have been measured for WW, WZ and ZZ pairs at 7 and 8 TeV pp collisions using the ATLAS detector. The measurements require heavy bosons to decay leptonically, including the Z->nu nu decay channel. The results are first obtained in phase space regions defined by the decay kinematics and then extrapolated to the full phase space. The measurements are compared to theoretical calculations at NLO and used to set accurate limits on anomalous triple gauge boson couplings.
