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

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

1  This LEES 2013F result is for the ${{\mathit K}^{\mp}}{{\mathit \pi}^{\pm}}$ mass-squared between 0.4 and 1.0 GeV${}^{2}$, and does not actually separate out the ${{\mathit K}^{*}}$.
2  AUBERT 2005S measures $\mathit N$( ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\overline{\mathit K}}^{*0}}$ )/$\mathit N$( ${{\mathit D}_{{s}}^{+}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ ), the ratio of the numbers of events observed, and similarly for the ${{\mathit D}^{-}}$.
3  FRABETTI 1994I and AITALA 1997B measure $\mathit N$( ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\overline{\mathit K}}^{*}{(892)}^{0}}$ )/$\mathit N$( ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{+}}$ ), the ratio of numbers of events observed, and similarly for the ${{\mathit D}^{-}}$.
