Measurement of the Masses and Lifetimes of B Hadrons at the Tevatron
  The latest results for the B Hadron sector at the Tevatron Collider are summarized. The properties of B Hadrons can be precisely measured at the Tevatron. In particularly we will focus on the masses and lifetimes. The new Tevatron results for the CP violation in B Hadrons will be also discussed.
