Production of single top quark - results from the Tevatron and the LHC

TL;DR

This paper reports recent measurements of single top quark production cross sections from the Tevatron and LHC experiments, covering different production channels and setting limits on the CKM matrix element |V_{tb}|.

Contribution

It provides the latest experimental results on single top quark production at multiple colliders, including separate analyses of different production channels and constraints on fundamental parameters.

Findings

Measured cross sections for s-channel, t-channel, and tW production.

Set lower limits on |V_{tb}| from single top measurements.

Compared results across Tevatron and LHC data.

Abstract

We present the most recent measurements of single top quark production cross section by the CDF and D0 experiments at the Fermilab Tevatron Collider and the ATLAS and CMS experiments at the Large Hadron Collider (LHC). The data were collected at the Tevatron corresponding to an integrated luminosity of up to 9.7 fb$^{-1}$ of proton-antiproton ($p\bar p$) collisions at a centre-of-mass energy of 1.96 TeV and at the LHC corresponding to an integrated luminosity of up to 4.9 fb$^{-1}$ of proton-proton ($pp$) collisions at a centre-of-mass energy of 7 TeV in 2011 and up to 20.3 fb$^{-1}$ at a centre-of-mass energy of 8 TeV in 2012. The measurements of single top quark production in $s$-channel, $t$-channel and associated production of a top quark and a $W$-boson ($tW$ production) are presented separately and lower limits on the CKM matrix element $|V_{tb}|$ from the single top quark cross section are set.
