Title: "Search for Single-Top-Quark Production at CDF II"

Abstract:

We present results from a search for single-top-quark production using one inverse femtobarn of data accumulated with the CDF detector. We select events with one charged lepton, large missing transverse energy, and two jets, where one jet is identified as a b-quark jet using displaced secondary-vertex information from the CDF silicon detector. We employ a matrix element analysis technique to improve separation of signal and background and greatly improve the sensitivity of our search.
