B Mixing and Lifetimes at the Tevatron
Résumé
The Tevatron collider at Fermilab provides a very rich environment for the study of b-hadrons. Both the D0 and CDF experiments have collected a sample of about 1 fb^{-1}. We report results on three topics: b-hadron lifetimes, polarization amplitudes and the decay width difference in Bs to Jpsi Phi, and Bs mixing.
