Description

At the LHC single top-quarks will be produced at a high rate corresponding to a third of the top-quark pair-production. In addition to the direct access to the CKM matrix element Vtb, single top-quark production is also sensitive to the existence of new heavy gauge bosons, forth generation quarks and various other new physics phenomena. Methods developed to optimize the selection of single top-quark events in the three production channels are presented and the potential for the cross-section measurements for different integrated luminosities is established. The measurements are dominated by systematic uncertainties and show the need for early strategies devoted to control of experimental biases, modeling effects and reliable background determinations.
