Summary

An updated measurement of the single top quark production cross section is presented using the full data set collected by the Collider Detector at Fermilab (CDF), corresponding to $9.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity from proton-antiproton collisions at 1.96 TeV center-of-mass energy. The events selected contain an imbalance in the total transverse momentum, jets identified as containing $b$ quarks, and no identified leptons. The sum of the $s$- and $t$-channel single top quark cross sections is measured to be $3.5{3}_{\ensuremath{-}1.16}^{+1.25}\text{ }\text{ }\mathrm{pb}$ and a lower limit on the magnitude of the top-to-bottom quark coupling, $|{V}_{tb}|$ of 0.63, is obtained at the 95% credibility level. These measurements are combined with previ
