Single Top Production at the Tevatron

TL;DR

This paper reports on the measurement of single top quark production at the Tevatron collider, using advanced multivariate analysis techniques to extract signals and measure cross sections, CKM matrix elements, and search for anomalous couplings.

Contribution

It provides the first combined measurements of single top production cross sections and Vtb at the Tevatron, including a search for anomalous Wtb couplings, using data from CDF and D0 collaborations.

Findings

Measured single top cross section consistent with Standard Model

Determined Vtb with improved precision

Set limits on anomalous Wtb couplings

Abstract

We present recent results of single top quark production in the lepton plus jet final state, performed by the CDF and D0 collaborations based on 7.5 and 5.4/fb of ppbar collision data collected at sqrt(s) = 1.96 TeV from the Fermilab Tevatron collider. Multivariate techniques are used to separate the single top signal from the backgrounds. Both collaborations present measurements of the single top quark cross section and the CKM matrix element Vtb. A search for anomalous Wtb coupling from D0 is also presented.
