Sažetak
For a long time, the B0 s -B¯0 s system has eluded a complete investigation of its observables. Only recently, the Tevatron experiments have accumulated sizable B0 s samples which allow a direct and precise study of the system properties. This contribution reviews the most up-to-date measurements by the CDF and DØ Collaborations of the B0 s -B¯0 s system parameters: the mass and decay-width differences, ∆ms and ∆Γs between the heavy and light B0 s mass eigenstates, the average decay width Γs and the CP-violating phase in the mixing φs.
