  • The cross section of a top-quark pair produced in association with a photon is measured in proton–proton collisions at a centre-of-mass energy of √ s = 8 TeV with 20.2 fb−1 of data collected by the ATLAS detector at the Large Hadron Collider in 2012. The measurement is performed by selecting events that contain a photon with transverse momentum pT > 15 GeV, an isolated lepton with large transverse momentum, large missing transverse momentum, and at least four jets, where at least one is… CONTINUE READING
