Contribution

It reports the first observation of t-channel single top quark production and combined measurements of s- and t-channel cross sections at the Tevatron.

Findings

First observation of t-channel production

Combined s- and t-channel cross section measurements

Extraction of |Vtb| matrix element

Abstract

While the heaviest known elementary particle, the top quark, has been discovered in 1995 by the CDF and D0 collaborations in ttbar events, it took 14 more years until the observation of single top quark production. In this article, we discuss recent studies of single top quark production by the CDF and D0 collaborations at the Tevatron. In particular, we present the measurement of single top quark s- and t-channel production combined, the first observation of t-channel production, the simultaneous measurement of s- and t-channel production cross sections as well as the extraction of the CMK matrix element |Vtb}|.
