Assumes $-2$ Re(${{\mathit \lambda}}$)/(1 + $\vert {{\mathit \lambda}}\vert ^2$) = 1. 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 a pure $\mathit CP$-odd final state ${{\mathit J / \psi}}{{\mathit K}_S^0}$ with the assumption that contributions from penguin diagrams are small. 5  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. 6  Measured using a pure $\mathit CP$-odd final state ${{\mathit J / \psi}}{{\mathit f}_{{{0}}}{(980)}}$. 7  Uses the time-dependent angular analysis of ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ decays assuming $\mathit CP$-violating angle ${{\mathit \beta}_{{{s}}}}$( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$) = 0.02. 8  Obtained from $\Delta \Gamma _{s}$ and $\Gamma _{s}$ fit with a correlation of 0.6. 9  Measured using the time-dependent angular analysis of ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ decays.
