$\mathit CP$ VIOLATION

$\mathit A_{CP}$ is defined as
${B( {{\mathit B}^{-}} \rightarrow {{\overline{\mathit f}}})–B( {{\mathit B}^{+}} \rightarrow {{\mathit f}})\over B( {{\mathit B}^{-}} \rightarrow {{\overline{\mathit f}}})+B( {{\mathit B}^{+}} \rightarrow {{\mathit f}})}$,
the $\mathit CP$-violation charge asymmetry of exclusive ${{\mathit B}^{-}}$ and ${{\mathit B}^{+}}$ decay.

$\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\overline{\mathit D}}^{0}}{{\mathit K}^{+}}$)

1  Supersedes AAIJ 2016L.
2  Uses ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{0}}$ for the favored mode, and ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ for the suppressed mode.
3  Uses ${{\mathit B}^{\pm}}$ $\rightarrow$ [ ${{\mathit K}^{\pm}}{{\mathit \pi}^{\mp}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ]$_{D}$ ${{\mathit h}^{\pm}}$ mode.
4  Corresponds to 90$\%$ confidence range $-0.15<\mathit A_{\mathit CP}<0.16$.
5  Corresponds to 90$\%$ confidence range $-0.07<\mathit A_{\mathit CP}<0.15$.
