We report a measurement of the WW production cross section in pp collisions
at 7 TeV. The WW leptonic decay channels are analyzed using data corresponding
to 1.02 /fb of integrated luminosity collected by the ATLAS detector during
2011 at the CERN Large Hadron Collider. With 414 observed WW candidate events
and an estimated background of 170±28 events, the measured WW production
cross section is 48.2±4.0(stat)±6.4(syst)±1.8(lumi) pb, in agreement with the Standard Model NLO prediction of
46±3 pb.Comment: 9 pages, proceedings of the DPF-2011 Conference, Providence, RI,
