${{\mathit D}^{0}}$ $\mathit CP$-VIOLATING DECAY-RATE ASYMMETRIES

This is the difference between ${{\mathit D}^{0}}$ and ${{\overline{\mathit D}}^{0}}$ partial widths for the decay to state ${{\mathit f}}$, divided by the sum of the widths:$
$ $\mathit A_{CP}({{\mathit f}}$) = [$\Gamma ({{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit f}}$) $−$ $\Gamma ({{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)] $/$ [$\Gamma ({{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit f}}$) + $\Gamma ({{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)].

$\mathit A_{CP}({{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$2 ${{\mathit \pi}^{0}}$) in ${{\mathit D}^{0}}$, ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$2 ${{\mathit \pi}^{0}}$
