${{\mathit D}^{\pm}}$ $\mathit CP$-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:$
$ $\mathit A_{CP}({{\mathit f}}$)= [$\Gamma ({{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit f}}$) $−$ $\Gamma ({{\mathit D}^{-}}$ $\rightarrow$ ${{\overline{\mathit f}}})]/[\Gamma ({{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit f}}$) + $\Gamma ({{\mathit D}^{-}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)].

${{\mathit A}}_{CP|S}({{\mathit K}^{+}}{{\overline{\mathit K}}^{*0}}$) in ${{\mathit D}^{\pm}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit K}^{+}}{{\mathit \pi}^{\pm}}$

The CP asymmetry is measured as ${{\mathit A}_{{{CP|S}}}}$ = [($\Delta A{}^{top-left}_{raw}$ + $\Delta A{}^{bottom-right}_{ raw}$) $−$ ($\Delta A{}^{top-right}_{ raw}$ + $\Delta A{}^{bottom-left}_{ raw}$)]/2 where $\Delta A{}^{pos}_{raw}$ is the difference between the signal and control channel raw asymmetries in the $\mathit pos$ Dalitz plot bin of the resonance.
