Abstract :
LEP has contributed substantially to our knowledge of B hadrons. Results will be presented on the lifetimes of weakly decaying B hadrons and on BB oscillations; in each case the LEP results are the most precise measurements of these quantities. The first observations of orbitally excited beauty mesons and of Σb and Σb∗ baryons, obtained during the past year, will be reviewed. Recent measurements of charmonium production in B decays and searches for Bc will also be presented.
