$\mathit CP$ 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.

$\mathit A_{CP}({{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$)

1  The second error includes both systematics and the uncertainties from $\mathit CP$ asymmetries in restricted regions of phase space.
2  HSU 2017 provides also measurement as a function of ${{\mathit K}^{+}}{{\mathit K}^{-}}$ invariant mass.
3  AAIJ 2014 reports $\mathit A_{CP}({{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$) = $-0.648$ $\pm0.070$ $\pm0.013$ $\pm0.007$ in the Dalitz plot region of ${{\mathit m}^{2}}_{\mathrm {{{\mathit K}^{+}} {{\mathit K}^{-}}}}$ $<$ 1.5 GeV${}^{2}$/c${}^{4}$. The third uncertainty is due to the $\mathit CP$ asymmetry of the ${{\mathit B}^{\pm}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit K}^{\pm}}$ reference mode uncertainty.
