 ALEP ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit Z}}$
1  Uses ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \eta}}$ decays.
2  AAIJ 2023P reports a ${{\mathit \tau}_{{{L}}}}$ value combined with AAIJ 2016AL result as ${{\mathit \tau}_{{{L}}}}$ = $1.452$ $\pm0.014$ $\pm0.007$ ps.
3  Measured using results in SIRUNYAN 2018BY for the heavy ${{\mathit B}_{{{s}}}^{0}}$ lifetime obtained from ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays and the average effective ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ lifetime, and magnitude squared of the $\mathit CP$-odd amplitude $\vert A_{\perp}\vert ^2$ = $0.250$ $\pm0.006$. The uncertainty includes all statistical and systematic contributions.
4  Measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit D}_{{{s}}}^{+}}$. The effective lifetime is translated into a decay width of $\Gamma _{L}$ = $0.725$ $\pm0.014$ $\pm0.009$ ps${}^{-1}$.
5  Measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}$ decays. There may still be CPV in the decay.
6  Uses the time-dependent angular analysis of ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ decays and assuming $\mathit CP$-violating angle ${{\mathit \beta}_{{{s}}}}$( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$) = 0.02.
7  Obtained from $\Delta \Gamma _{s}$ and $\Gamma _{s}$ fit with a correlation of 0.6.
8  Measured using the time-dependent angular analysis of ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ decays.
9  Uses ${{\mathit \phi}}{{\mathit \phi}}$ correlations from ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{(*)+}}{{\mathit D}_{{{s}}}^{(*)-}}$.
