The branching fraction measurements are for an admixture of ${{\mathit B}}$ mesons and baryons at energies above the ${{\mathit \Upsilon}{(4S)}}$. Only the highest energy results (LHC, LEP, Tevatron, S${{\mathit p}}{{\overline{\mathit p}}}$S) are used in the branching fraction averages. In the following, we assume that the production fractions are the same at the LHC, LEP, and at the Tevatron.
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.
The modes below are listed for a ${{\overline{\mathit b}}}$ initial state. ${{\mathit b}}~$modes are their charge conjugates. Reactions indicate the weak decay vertex and do not include mixing.
