1  AAIJ 2023AT reports ${{\mathit \phi}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{s}$ = $-0.074$ $\pm0.069$ rad and $\vert \lambda \vert $ = $1.009$ $\pm0.030$. Measured using a time-dependent fit to ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \phi}}$ decays, assuming independence of the helicity of the ${{\mathit \phi}}{{\mathit \phi}}$ decay.
2  AAIJ 2023AT also reports polarisation-dependent results assuming that the longitudinal weak phase is $\mathit CP$-conserving and that there is no direct $\mathit CP$ violation.
3  Measured using a time-dependent fit to ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \phi}}$ decays, assuming independence of the helicity of the ${{\mathit \phi}}{{\mathit \phi}}$ decay.
4  AAIJ 2019AP reports ${{\mathit \phi}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{s}$ = $-0.073$ $\pm0.115$ $\pm0.027$ rad and $\vert \lambda \vert $= $0.99$ $\pm0.05$ $\pm0.01$. Measured using a time-dependent fit to ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \phi}}$ decays, assuming independence of the helicity of the ${{\mathit \phi}}{{\mathit \phi}}$ decay.
5  AAIJ 2019AP reports also polarisation-dependent results assuming that the longitudinal weak phase is $\mathit CP$-conserving and that there is no direct $\mathit CP$ violation, giving ${{\mathit \phi}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{ s,\parallel}$ = $0.014$ $\pm0.055$ $\pm0.011$ rad and ${{\mathit \phi}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{ s,\perp}$ = $0.044$ $\pm0.059$ $\pm0.019$ rad.
6  AAIJ 2014AE value measured in ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \phi}}$ decays. Also reports ${{\mathit \phi}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{s}$ = $-0.17$ $\pm0.15$ $\pm0.03$ rad.
7  AAIJ 2013AY uses ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \phi}}$ mode, and reports the 68$\%$ CL interval of ${{\mathit \phi}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{s}$ = $-2$ ${{\mathit \beta}}{}^{{{\mathit s}} {{\overline{\mathit s}}} {{\mathit s}}}_{s}$ as $\lbrack{}-2.46$, $-0.76$] rad.
