Abstract

The production of single top quarks occurs via three processes: t-channel, s-channel and tW associated production. The LHC experiments have observed single top production via t-channel at 7 TeV and measured its cross section, providing a measurement of |Vtb| with an uncertainty at the 10% level. Studies are in place to observe tW associated production with a sensitivity close to 3sigma and the first limits on the production cross section for s-channel are set. Other studies based on single top topologies, like flavor changing neutral currents (FCNC) are also being performed.
