Heavy baryon production and decay

The branching ratio B(Λc→pK^-π⁺) normalizes the production and decay of charmed and bottom baryons. At present, this crucial branching ratio is extracted dominantly from B̄→baryons analyses. This paper questions several of the underlying assumptions and predicts sizable B̄→D(*)NN^'X transitions, which were traditionally neglected. It predicts B(Λc→pK^-π⁺) to be larger (0.07±0.02) than the world average. Some consequences are briefly mentioned. Several techniques to measure B(Λc→pK^-π⁺) are outlined with existing or soon available data samples. By equating two recent CLEO results, an appendix obtains B(D⁰→K^-π⁺)=0.035±0.002, which is somewhat smaller than the current world average.
