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

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

$\mathit A_{\mathit CP}$(2 ${{\mathit \pi}^{\pm}}{{\mathit \pi}^{\mp}}$2 ${{\mathit \pi}^{0}}$) in ${{\mathit D}^{\pm}}$ $\rightarrow$ 2 ${{\mathit \pi}^{\pm}}{{\mathit \pi}^{\mp}}$2 ${{\mathit \pi}^{0}}$
