Measurement of the Single Top Quark Production Cross Section and |V[subscript tb]| in Events with One Charged Lepton, Large Missing Transverse Energy, and Jets at CDF

We report a measurement of single top quark production in proton-antiproton collisions at a center-of-mass energy of √s = 1.96  TeV using a data set corresponding to 7.5  fb[superscript -1] of integrated luminosity collected by the Collider Detector at Fermilab. We select events consistent with the...

Description
Summary:We report a measurement of single top quark production in proton-antiproton collisions at a center-of-mass energy of √s = 1.96  TeV using a data set corresponding to 7.5  fb[superscript -1] of integrated luminosity collected by the Collider Detector at Fermilab. We select events consistent with the single top quark decay process t → Wb → ℓνb by requiring the presence of an electron or muon, a large imbalance of transverse momentum indicating the presence of a neutrino, and two or three jets including at least one originating from a bottom quark. An artificial neural network is used to discriminate the signal from backgrounds. We measure a single top quark production cross section of 3.04[+0.57 over -0.53]  pb and set a lower limit on the magnitude of the coupling between the top quark and bottom quark |V[subscript tb]| > 0.78 at the 95% credibility level.
