${{\mathit D}^{0}}$ $\mathit CP$-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 $( ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)].

$\mathit A_{CP}(({{\mathit K}^{-}}{{\mathit \pi}^{+}})_{{\mathit P}{\mathrm -wave}}$ (${{\mathit K}^{+}}{{\mathit \pi}^{-}})_{{\mathit S}{\mathrm -wave}}$) in ${{\mathit D}^{0}}$ $\rightarrow({{\mathit K}^{-}}{{\mathit \pi}^{+}})_{{\mathit P}{\mathrm -wave}}$ (${{\mathit K}^{+}}{{\mathit \pi}^{-}})_{{\mathit S}{\mathrm -wave}}$ , ${{\overline{\mathit D}}^{0}}$ $\rightarrow$c.c.
