Measurement of $Wgamma$ and $Zgamma$ production cross sections in $pp$ collisions at $7~TeV$ and limits on anomalous triple gauge couplings with the ATLAS detector

In this letter, we present measurements of $W(l u)gamma$ and $Z(ll)gamma$ ($l=e,mu$) productions in $1.02~fb^{-1}$ of $7~TeV$ $pp$ collision data recorded at ATLAS experiment. Cross sections and kinematic distributions are measured and compared to SM expectations. No evidence for physics beyond the SM is observed, and therefore limits on anomalous $WWgamma$ and $ZZgamma/Zgammagamma$ couplings are determined.
