Measurement of the WW$+$WZ Production Cross Section in Proton-Proton Collisions at sqrt(s) $=$ 7 TeV with the ATLAS Detector in the semileptonic decay channel

A measurement of the WW/WZ production cross section is presented in pp collisions at $\surd $s $=$ 7 TeV. The cross section is measured in the WW/WZ$\to $lvqqbar decay channel using data gathered by the ATLAS detector at the Large Hadron Collider during 2011 and corresponding to an integrated luminosity of 4.7 $\pm $ 0.2 fb$^{\mathrm{-1}}$. This cross section measurement will be compared to the Standard Model expectation value of 63.4 $\pm $ 2.6 pb and the anomalous triple gauge coupling limits for gammaWW and WWZ will also be addressed.
