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

$\mathit A_{\mathit CP}$( ${{\mathit K}_L^0}$ ${{\mathit e}^{\pm}}{{\mathit \nu}}$ ) in ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit K}_L^0}$ ${{\mathit e}^{+}}{{\mathit \nu}_{{e}}}$ , ${{\mathit D}^{-}}$ $\rightarrow$ ${{\mathit K}_L^0}$ ${{\mathit e}^{-}}{{\overline{\mathit \nu}}_{{e}}}$
