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

$\mathit A_{CP}$( ${{\mathit K}^{*}{(892)}^{0}}$ ( ${{\mathit K}^{-}}{{\mathit \pi}^{+}}$ )$_{{\mathit S}{\mathrm -wave}}$) in ${{\mathit D}^{0}}$ , ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\mathit K}^{*}{(892)}^{0}}$ ( ${{\mathit K}^{-}}{{\mathit \pi}^{+}}$ )$_{{\mathit S}{\mathrm -wave}}$
