Query: Measurement of the CP-Violating Phase beta_s in B0s -> J/Psi Phi Decays
  with the CDF II Detector   We present a measurement of the \CP-violating parameter \betas using
approximately 6500 $\BsJpsiPhi$ decays reconstructed with the CDF\,II detector
in a sample of $p\bar p$ collisions at $\sqrt{s}=1.96$ TeV corresponding to 5.2
fb$^{-1}$ integrated luminosity produced by the Tevatron Collider at Fermilab.
We find the \CP-violating phase to be within the range $\betas \in [0.02, 0.52]
\cup [1.08, 1.55]$ at 68% confidence level where the coverage property of the
quoted interval is guaranteed using a frequentist statistical analysis. This
result is in agreement with the standard model expectation at the level of
about one Gaussian standard deviation. We consider the inclusion of a potential
$S$-wave contribution to the $\Bs\to J/\psi K^+K^-$ final state which is found
to be negligible over the mass interval $1.009 < m(K^+K^-)<1.028 \gevcc$.
Assuming the standard model prediction for the \CP-violating phase \betas, we
find the \Bs decay width difference to be $\deltaG = 0.075 \pm
0.035\,\textrm{(stat)} \pm 0.006\,\textrm{(syst)} \ps$. We also present the
most precise measurements of the \Bs mean lifetime $\tau(\Bs) = 1.529 \pm
0.025\,\textrm{(stat)} \pm 0.012\,\textrm{(syst)}$ ps, the polarization
fractions $|A_0(0)|^2 = 0.524 \pm 0.013\,\textrm{(stat)} \pm
0.015\,\textrm{(syst)}$ and $|A_{\parallel}(0)|^2 = 0.231 \pm
0.014\,\textrm{(stat)} \pm 0.015\,\textrm{(syst)}$, as well as the strong phase
$\delta_{\perp}= 2.95 \pm 0.64\,\textrm{(stat)} \pm 0.07\,\textrm{(syst)}
\textrm{rad}$. In addition, we report an alternative Bayesian analysis that
gives results consistent with the frequentist approach.
