摘要

The observation of the electroweak production of single-top-quarks is made using 255 pb of proton-proton collision data recorded at s=5.02 TeV with the ATLAS detector at the Large Hadron Collider. An event selection is used to identify single-top-quark candidates arising from t-channel production with the top quark decaying semi-leptonically. Events passing the selection are then used to measure the inclusive cross-section for the combined production of single-top-quarks and antiquarks, σ(tq+t¯q), and the ratio R between these two. They are measured to be σ(tq+t¯q)=27.1 (stat.) (syst.) pb and R =2.73 (stat.) (syst.). The individual single-top-quark (tq) and single-top-antiquark (t¯q) production cross-sections are measured to be σ(tq)=19.8 (stat.) (syst.) pb and σ(t¯q)=7.3 (stat.) (syst.) pb. All measurements are in good agreement with the Standard Model predictions.
