${{\mathit D}_{{{s}}}^{+}}−{{\mathit D}_{{{s}}}^{-}}$ $\mathit CP$-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:$
$ $\mathit A_{CP}({{\mathit f}}$)= [$\Gamma ({{\mathit D}_{{{s}}}^{+}}$ $\rightarrow$ ${{\mathit f}}$) $−$ $\Gamma ({{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)] $/$ [$\Gamma ({{\mathit D}_{{{s}}}^{+}}$ $\rightarrow$ ${{\mathit f}})+\Gamma ({{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)].

$\mathit A_{CP}({{\mathit K}^{\pm}}{{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$) in ${{\mathit D}_{{{s}}}^{\pm}}$ $\rightarrow$ ${{\mathit K}^{\pm}}{{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$
