Query: Updated Measurement of the Single Top Quark Production Cross Section and
  $V{tb}$ in the Missing Transverse Energy Plus Jets Topology in $p\bar{p}$
  Collisions at $\sqrt{s} = 1.96$ TeV   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) and corresponding to 9.5 fb${}^{-1}$ 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 energy, jets identified
as originating from $b$ quarks, and no identified leptons. The sum of the $s$-
and $t$-channel single top quark cross sections is measured to be
$3.53_{-1.16}^{+1.25}$ pb and a lower limit on $V_{tb}$ of 0.63 is obtained at
the 95% credibility level. These measurements are combined with previously
reported CDF results obtained from events with an imbalance in total transverse
energy, jets identified as originating from $b$ quarks, and exactly one
identified lepton. The combined cross section is measured to be
$3.02_{-0.48}^{+0.49}$ pb and a lower limit on $V{tb}$ of 0.84 is obtained at
the 95% credibility level.
