A measurement of single top-quark production in the s-channel is performed in proton--proton collisions at a centre-of-mass energy of TeV with the ATLAS detector at the CERN Large Hadron Collider. The dataset corresponds to an integrated luminosity of 139 fb. The analysis is performed on events with an electron or muon, missing transverse momentum and exactly two -tagged jets in the final state. A discriminant based on matrix element calculations is used to separate single top-quark s-channel events from the main background contributions, which are top-quark pair production and -boson production in association with jets. The observed (expected) signal significance over the background-only hypothesis is 3.3 (3.9) standard deviations, and the measured cross-section is pb, consistent with the Standard Model prediction of pb.
