$\mathit CP$ 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.

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

1  AAIJ 2014BO reports also $\mathit CP$ asymmetries in restricted regions of phase space.
2  AAIJ 2014 reports $\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{+}}$ ) = $0.584$ $\pm0.082$ $\pm0.027$ $\pm0.007$ in the Dalitz plot region of ${{\mathit m}^{2}}_{\mathrm { {{\mathit \pi}^{+}} {{\mathit \pi}^{-}} }}$ $>$ 15 GeV${}^{2}$/c${}^{4}$ or ${{\mathit m}^{2}}_{\mathrm { {{\mathit \pi}^{+}} {{\mathit \pi}^{-}} }}<$ 0.4 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.
