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

$\mathit A_{\mathit CP}({{\mathit \phi}{(1680)}}{{\mathit \pi}^{\pm}}$) in ${{\mathit D}^{\pm}}$ $\rightarrow$ ${{\mathit \phi}{(1680)}}{{\mathit \pi}^{\pm}}$
