Measurement of the $t\bar{t}\gamma$ production cross section in proton-proton collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector

CERN-LHC-ATLAS. Measurements of the cross section for $t\bar{t}\gamma$ production using the single lepton (e or mu) channel in proton-proton collisions at a centre-of-mass energy of 8 TeV with 20.2 fb^-1 of data collected in 2012.
