Description
The first measurement of CP violation phase beta_s in Bs -> J/psi phi
decays in 2007 generated considerable interest. The interest was caused by
the small deviation from the SM. While not sufficiently significant,
together with other measurements it is suggestive of a possible new physics
contribution. In the subsequent update using 2.8 fb-1 of data collected by
CDF II detector deviation from the SM further increased. We present latest
CDF results on the mean decay width Gamma_s and CP violating phase beta_s,
based on an angular- and time-dependent analysis of the Bs -> J/psi phi
decays, including determination of the flavor of the Bs meson at production
time.
