${{\mathit D}^{0}}$ $\mathit CP$-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.
