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

$\mathit A_{CP}$( ${{\mathit K}_{{{1}}}^{*}{(1270)}^{+}}$ ${{\mathit K}^{-}}$ $\rightarrow$ ${{\mathit \rho}^{0}}{{\mathit K}^{+}}{{\mathit K}^{-}}$) in ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}_{{{1}}}^{*}{(1270)}^{+}}{{\mathit K}^{-}}$, ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ c.c.
