The CDF detector has collected between February 2002 and February
2004 a physics quality sample of about 270 pb-1. Three topics under study,
using the entire sample or part thereof, are covered here: exclusive decays
lifetimes, time dependent polarization amplitudes of B(d) --> J/psi K*0 and
B_s --> J/psi phi decays, and mixing in B(d) decays.
