The search for single top quarks at the LHC

We report on the predictions of the Standart Model for the single top-quark production at LHC and on the analysis strategies adopted by CMS and ATLAS for the single top-quark search. The Standard Model predicts the production of single top quark through three electroweak processes in the LHC energy reach, referred to as extit{t,s and tW channels}, resulting in distinct topologies and backgrounds. Different analysis strategies to search for the single top have been developed by CMS and ATLAS experiments. For the 14 TeV center of mass energy scenario all the channels have been considered, while for the 10 TeV scenario a specific strategy has been developed only for the t-channel and has been applied on Monte Carlo samples assuming an integrated luminosity of 200 $pb^{-1}$.
