These branching fractions are actually an average over weakly decaying ${{\mathit b}}$-baryons weighted by their production rates at the LHC, LEP, and Tevatron, branching ratios, and detection efficiencies. They scale with the ${{\mathit b}}$-baryon production fraction B( ${{\mathit b}}$ $\rightarrow$ ${{\mathit b}}$ -baryon).
The branching fractions B( ${{\mathit b}}$ -baryon $\rightarrow$ ${{\mathit \Lambda}}{{\mathit \ell}^{-}}{{\overline{\mathit \nu}}_{{{{\mathit \ell}}}}}$ anything) and B( ${{\mathit \Lambda}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit \Lambda}_{{c}}^{+}}{{\mathit \ell}^{-}}{{\overline{\mathit \nu}}_{{{{\mathit \ell}}}}}$ anything) are not pure measurements because the underlying measured products of these with B( ${{\mathit b}}$ $\rightarrow$ ${{\mathit b}}$ -baryon) were used to determine B( ${{\mathit b}}$ $\rightarrow$ ${{\mathit b}}$ -baryon), as described in the note ``Production and Decay of ${{\mathit b}}$-Flavored Hadrons.''
For inclusive branching fractions, $\mathit e.g.,$ ${{\mathit B}}$ $\rightarrow$ ${{\mathit D}^{\pm}}$ anything, the values usually are multiplicities, not branching fractions. They can be greater than one.
