${{\mathit D}_{{{s}}}^{+}}−{{\mathit D}_{{{s}}}^{-}}$ $\mathit CP$-VIOLATING DECAY-RATE ASYMMETRIES

This is the difference between ${{\mathit D}_{{{s}}}^{+}}$ and ${{\mathit D}_{{{s}}}^{-}}$ partial widths for the decay to state ${{\mathit f}}$, divided by the sum of the widths:$
$ $\mathit A_{CP}({{\mathit f}}$)= [$\Gamma $( ${{\mathit D}_{{{s}}}^{+}}$ $\rightarrow$ ${{\mathit f}}$ ) $−$ $\Gamma $( ${{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\overline{\mathit f}}}$ )] $/$ [$\Gamma $( ${{\mathit D}_{{{s}}}^{+}}$ $\rightarrow$ ${{\mathit f}}$ )+$\Gamma $( ${{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\overline{\mathit f}}}$ )].

$\mathit A_{CP}$( ${{\mathit \eta}}{{\mathit \pi}^{\pm}}{{\mathit \pi}^{0}}$ ) in ${{\mathit D}_{{{s}}}^{\pm}}$ $\rightarrow$ ${{\mathit \eta}}{{\mathit \pi}^{\pm}}{{\mathit \pi}^{0}}$
