1  Based on $\Delta \Gamma $ = $\Gamma _{H}$ $−$ $\Gamma _{{{\mathit B}^{0}}}$ = $-0.05$ $\pm0.004$ $\pm0.004$ ps${}^{-1}$ and ${\mathit \tau}_{{{\mathit B}^{0}}}$ = $1.517$ $\pm0.004$ ps. The first error is due to the combined $\Delta \Gamma $ uncertainty and the second is from ${\mathit \tau}_{{{\mathit B}^{0}}}$ uncertainty.
2  Measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays with 0.9240 $<$ m(${{\mathit \pi}}{{\mathit \pi}}$) $<$ 1.0204 GeV, which is dominated by the ${{\mathit f}_{{{0}}}{(980)}}$ resonance, making it a $\mathit CP$-odd state.
3  Measured using ${{\mathit J / \psi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mode with 0.880 $<$ $\mathit m({{\mathit \pi}}{{\mathit \pi}}$) $<$ 1.080 GeV/c${}^{2}$, which is mostly ${{\mathit J / \psi}}{{\mathit f}{(0980)}}$ mode, a pure $\mathit CP$-odd final state.
4  Measured using ${{\mathit B}_{{{s}}}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays which, in the limit of ${{\mathit \phi}_{{{s}}}}$ = 0 and $\vert {{\mathit \lambda}}\vert $ = 1, correspond to ${{\mathit B}_{{{sH}}}^{0}}$ decays.
5  Measured using a pure $\mathit CP$-odd final state ${{\mathit J / \psi}}{{\mathit f}_{{{0}}}{(980)}}$.
