The author discusses results from the Tevatron experiments on mixing and CP-violation in B{sub s} mesons, including the observation of B{sub s} oscillations and the first precision measurement of the mixing frequency, as well as a measurement of the lifetime difference [Delta][Lambda]{sub s} and the first measurement of the CP-violating phase [delta]{sub s}. The author also briefly reports on the observation of four new bottom baryons at CDF.

The authors discuss the results from the Tevatron experiments on mixing and CP violation in the B{sub s}°-{bar B}{sub s}° system, with particular emphasis to the updated measurements of the decay-width difference [Delta][Lambda]{sub s} and the first measurement of the CP-violating phase [beta]{sub s} using flavor tagging information. They also briefly review the charge asymmetry measurements in semileptonic B{sub s}° decays and in B{sup {+-}} → J/[psi]K{sup {+-}} decays.

The two collider experiments at the Tevatron, CDF and D0, have made a lot of progress in B{sub s} lifetime difference measurements. Here, they have included 3 different channels of measurements, namely, B{sub s} {yields} J/{psi} + {phi}, B{sub s} {yields} K{sup +}K{sup -} and B{sub s} {yields} D{sub s}{sup (*)+}D{sub s}{sup (*)-}. Combining all the available measurements, they have obtained {Delta}{Lambda}{sub s} = 0.097{sub -0.042}{sup +0.041} ps{sup -1} and {bar {tau}} = 1/{Lambda}{sub s} = 1.461 {+-} 0.030 ps. {Delta}{Lambda}{sub s} is now 2.3 {sigma} away from zero.
