We present the status and prospects of single-top-quark production searches at CDF.
In p-pbar collisions, individual top quarks are expected to be produced in association with bottom quarks mainly through the exchange of an off-mass-shell W boson (s-channel), or the W-gluon fusion process (t-channel). We select events with one charged lepton, high missing transverse energy and at least 2 jets, one of which is identified as a b-quark using the CDF Silicon detector. It is a challenge to distinguish the single top signal from significant backgrounds from W+jets processes with heavy flavour, eg Wbb, Wcc, Wc. We perform a combined search for the s- and t- channels, along with individual searches for each channel.
