The BββΟc0βKβ decay which has no visible factorizable
amplitude, could be induced by the Cabibbo-allowed, color-favored BββDsβDβ0, BββDsβ0βD0 and BβDsββDβ via the
rescattering of these charmed mesons to ΟcoβKβ. In this talk I would
like to discuss a recent calculation \cite{Colangelo} of these effects for
BββΟc0βKβ and BββJ/ΟKβ decays. We find that
charmed scattering effects seem capable of producing a large BββΟc0βKβ branching ratio measured by the Babar and Belle Collaboration
and make a significant contribution to the BββJ/ΟKβ branching
ratios in agreement with experiments.Comment: Talk at the International Workshop on QCD: QCD@Work 2003 - Conversano
