Many measurements of ${{\mathit B}}$ decays involve admixtures of ${{\mathit B}}$ hadrons. Previously we arbitrarily included such admixtures in the ${{\mathit B}^{\pm}}$ section, but because of their importance we have created two new sections: “${{\mathit B}^{\pm}}/{{\mathit B}^{0}}$ Admixture” for ${{\mathit \Upsilon}{(4S)}}$ results and “${{\mathit B}^{\pm}}/{{\mathit B}^{0}}/{{\mathit B}_{{s}}^{0}}/{{\mathit b}}$-baryon Admixture” for results at higher energies. Most inclusive decay branching fractions and ${{\mathit \chi}_{{b}}}$ at high energy are found in the Admixture sections. ${{\mathit B}^{0}}-{{\overline{\mathit B}}^{0}}$ mixing data are found in the ${{\mathit B}^{0}}$ section, while ${{\mathit B}_{{s}}^{0}}-{{\overline{\mathit B}}_{{s}}^{0}}$ mixing data and ${{\mathit B}}-{{\overline{\mathit B}}}$ mixing data for a ${{\mathit B}^{0}}/{{\mathit B}_{{s}}^{0}}$ admixture are found in the ${{\mathit B}_{{s}}^{0}}$ section. $\mathit CP$-violation data are found in the ${{\mathit B}^{\pm}}$, ${{\mathit B}^{0}}$, and ${{\mathit B}^{\pm}}{{\mathit B}^{0}}$ Admixture sections. ${{\mathit b}}$-baryons are found near the end of the Baryon section. Recently, we also created a new section: “$\mathit V_{ {{\mathit c}} {{\mathit b}} }$ and $\mathit V_{ {{\mathit u}} {{\mathit b}} }$ CKM Matrix Elements.”

The organization of the ${{\mathit B}}$ sections is now as follows, where bullets indicate particle sections and brackets indicate reviews.
