Measurement of 𝑡-channel single-top-quark production in 𝑝𝑝 collisions at √𝑠 = 5.02 TeV with the ATLAS detector

Original language description

The observation of the electroweak production of single-top-quarks is made using 255 pb−1 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 Rt between these two. They are measured to be σ(tq+t¯q)=27.1−4.1 +4.4(stat.)−3.7 +4.4(syst.) pb and Rt=2.73−0.82 +1.43(stat.)−0.29 +1.01(syst.). The individual single-top-quark (tq) and single-top-antiquark (t¯q) production cross-sections are measured to be σ(tq)=19.8−3.1 +3.9(stat.)−2.2 +2.9(syst.) pb and σ(t¯q)=7.3−2.1 +3.2(stat.)−1.5 +2.8(syst.) pb. All measurements are in good agreement with the Standard Model predictions.
