Title: A Study of New B -> J/psi K(*)0 X decays

Abstract: 

Exclusively reconstructed B -> J/psi X decays have been used for a variety
of B physics measurements including masses, lifetimes, polarizations, and
CP violation. These modes are especially useful at hadronic accelerators
where J/psi -> mu mu provides a clean trigger to separate the B decays from
the large backgrounds. 

We present a study of several previously unobserved exclusively
reconstructed B -> J/psi K(*)0 X decays.  These decays have relatively
large branching fractions and are promising for a variety of CKM related 
B physics measurements including several CP violation possibilities.
