6 B-factories Legacy Book 61st Meeting, SLAC, Oct 2009 Inter-correlation Several cases where papers involve charmed baryons but main thrust of analysis belongs in another section: Exclusive B decays to charmed baryons (→ baryonic B decays) Inclusive momentum spectra of baryons (→ fragmentation and/or baryonic B decays) Λ c + Λ c − pair production with popcorn (→ fragmentation) Λ c + Λ c − pair production in ISR events (→ ISR? Exotics?) Section editors for baryonic B decays & fragmentation contacted. Resolution: those analysis topics will be covered elsewhere (i.e. not by us) Subset of the above include results on charmed baryon spectroscopy / decays in same paper. In those cases, we’ll cover that part. Example: B − → Λ c + p π − includes results on Σ c resonances.

7 B-factories Legacy Book 71st Meeting, SLAC, Oct 2009 Contributors Confirmed (beside section editors) BaBar: Pat Burchat* Belle: Ruslan Chistov* Un-confirmed BaBar: 2 Belle: 0 * Volunteer for reading/editing/criticism

8 B-factories Legacy Book 81st Meeting, SLAC, Oct 2009 Comments Would like to be able to say something about absolute charmed baryon branching fractions. Preliminary result from Belle, but no published results from either Belle or BABAR. (Analysis started on BABAR side but almost zero manpower.) This is worth doing!
