Abstract

Recent measurements of B hadron properties carried out in sqrt(s)=1.96 TeV p/p-bar collisions at the Tevatron are reviewed. Included are measurements of the Bc+ meson lifetime, using J/psi+l+X final states, and the mass, using J/psi+pi final states, a flavor specific measurement of the Bs0 lifetime in Ds+pi+X decays, simultaneous measurements of the Bs0 lifetime and lifetime difference in J/psi+phi decays, the first direct evidence and mass measurements of the Xi_b- baryon, and measurements of the polarization of 1S charmonium. For all measurements, charge conjugate modes are included.
