Abstract

ATLAS measurements of single top-quark processes are summarised. Measurements using data recorded at the LHC proton-proton collider at centre-of-mass energies of √s=7 TeV and 8 TeV are presented. The measurements are performed using the semi-leptonic decay mode of the top quark. Production cross-sections for the t-channel and W_t modes of single top-quark production and the extraction of the CKM matrix element |V_tb| are shown. All measurements are compared to theoretical calculations. In addition, the s-channel production mode is explored along with limits on exotic production modes.
