Single top measurements at the LHC: $s$-channel and $Wt$ production

This paper summarises the latest experimental results on single top quark physics by the ATLAS and CMS collaborations using LHC proton--proton collisions at $\sqrt{s}=8 \rm \ TeV$. Searches for single top-quark production in the $s$-channel and associated $Wt$ mode are presented and a determination of the CKM matrix element $|V_{tb}|$ is discussed. Evidence for $s$-channel production is reported by the ATLAS collaboration and the $Wt$ process has been observed at the LHC.
