Motivation
Tests electroweak physicsBackground to Higgs search
Set limits on anomalous triple gauge couplings (aTGC)
neutral TGCs not in SM
ATLAS diboson x-sections measured high at 7 TeV

The ATLAS detectorInner detector• within solenoid magnet• pixels for vertex location• silicon detector tracks charged particles• |η| < 2.5
EM & hadronic calorimeters• measures energy deposited• |η| < 4.9
