Description
The CDF experiment presents improved bounds on the CP-violating phase
beta_s and on the decay-width difference DeltaGamma_s of the neutral B_s0
meson system.
We use 6500 B_s0 --> J/psi Phi decays collected by the dimuon trigger and
reconstructed in a sample corresponding to 5.2 fb^{-1} of dat
Besides exploiting a two-fold increase in statistics with respect to the
previous measurement, several improvements have been introduced in the
analysis including
a fully data-driven flavor-tagging calibration and proper treatment of
possible S-wave contributions. In addition, the
first observation of suppressed B0_s --> J/Psi K* and Bs-->J/psiK_s will
be reported.
