Title:
"Search for Single-Top-Quark Production at CDF II"
Abstract:
The electroweak production of single top quarks has been sought after
since the discovery of the top quark more than 10 years ago. The
measurement of the cross section for single top quarks provides sensitivity
to the CKM element Vtb and
is sensitive to various models of physics beyond the standard model.
CDF uses several multivariate techniques to search for s-channel and
t-channel single-top production, as well as the combined process, using 1
fb-1 of proton-antiproton collision data. Results are given for two of
these techniques, one using likelihood functions and one using neural
networks.
