$\mathit CP$ 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.

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