Study of CP violation in $$B_s \rightarrow J/\psi \phi$$ decays at CDF
The first measurement of the CP violation phase {beta}{sub s} in B{sub s} {yields} 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{sup -1} of data collected by the CDF II detector, the significance of the deviation from the SM further increased. We present latest CDF results on the mean decay width {Lambda}{sub s} and CP violating phase {beta}{sub s}, based on an angular- and time-dependent analysis of the B{sub s} {yields} J/{Psi}{phi} decays, including determination of the flavor of the B{sub s} meson at production time.
