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