$\mathit CP$ VIOLATION PARAMETERS in ${{\mathit B}_{{s}}^{0}}$

r$_{B}$( ${{\mathit B}_{{s}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{s}}^{\mp}}{{\mathit K}^{\pm}}$ )

INSPIRE   PDGID:
S086ARX
r$_{B}$ and $\delta _{B}$ are the amplitude ratio and relative strong phase between the amplitudes of $\mathit A$( ${{\mathit B}_{{s}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{s}}^{+}}{{\mathit K}^{-}}$ ) and $\mathit A$( ${{\mathit B}_{{s}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{s}}^{-}}{{\mathit K}^{+}}$ ),

1  Measured in ${{\mathit B}_{{s}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{s}}^{\mp}}{{\mathit K}^{\pm}}$ decays, constraining $-2{{\mathit \beta}_{{s}}}$ by the measurement of ${{\mathit \phi}_{{s}}}$ = $-0.030$ $\pm0.033$ from HFLAV.
2  Measured in ${{\mathit B}_{{s}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{s}}^{\mp}}{{\mathit K}^{\pm}}$ decays, constraining $-2{{\mathit \beta}_{{s}}}$ by the measurement of ${{\mathit \phi}_{{s}}}$ = $0.01$ $\pm0.07$ $\pm0.0$ from AAIJ 2013AR. At 68$\%$ CL.
