Abstract
We present improved bounds on the CP-violating phase β s J/Ψφ and on the decay-width difference ΔΓ of the neutral B s 0 meson system obtained by the CDF experiment at the Tevatron collider. We use 6500 B s 0 → J/ Ψφ decays collected by the dimuon trigger and reconstructed in a sample corresponding to integrated luminosity of 5.2 fb -1. 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 flavour-tagging calibration and proper treatment of possible S-wave contributions.
