Abstract (data abstract)
CERN-LHC-ATLAS. Measurements of the inclusive and differential fiducial cross-sections for ttbar+photon production using leptonic channels in proton-proton collisions at a centre-of-mass energy of 13 TeV with 36.1 fb^-1 of data collected in 2015 and 2016. The fiducial region for single lepton channel is defined as: - Exactly 1 electron or muon, which has pT > 25 GeV and |eta| < 2.5. - Exactly 1 photon, which has pT > 20 GeV and |eta| < 2.37. - At least 4 jets, which have pT > 25 GeV and |eta| < 2.5. - At least 1 b-jet - The deltaR between the lepton and the photon is larger than 1.0. The fiducial region for dilepton channel is defined as: - Exactly 2 leptons, where lepton can be electron or muon, which have pT > 25 GeV and |eta| < 2.5. - Exactly 1 photon, which has pT > 20 GeV and |eta| < 2.37. - At least 2 jets, which have pT > 25 GeV and |eta| < 2.5. - At least 1 b-jet - The minimum deltaR between the leptons and the photon is larger than 1.0.
