Abstract
We report the observation of and decays to doubly charmed final states where and are fully reconstructed and K is either a or a We use a sample of million events collected between 1999 and 2002 with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center. The 22 possible B decays to are reconstructed exclusively and the corresponding branching fractions or limits are determined. The branching fractions of the and of the to are found to be A search for decays to orbitally excited states, is also performed. No statistically significant contributions from and to the final state are found and we set 90% C.L. limits on their production rates.
