$\mathit CP$ VIOLATION

$\mathit A_{CP}$ is defined as
${B( {{\overline{\mathit B}}} \rightarrow {{\overline{\mathit f}}})–B( {{\mathit B}} \rightarrow {{\mathit f}})\over B( {{\overline{\mathit B}}} \rightarrow {{\overline{\mathit f}}})+B( {{\mathit B}} \rightarrow {{\mathit f}})}$,
the $\mathit CP$-violation charge asymmetry of inclusive ${{\mathit B}^{\pm}}$ and ${{\mathit B}^{0}}$ decay.

1  Measured from sum of exclusive modes through ${{\mathit K}^{+}}$, ${{\mathit K}^{+}}{{\mathit \pi}^{0}}$, ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$, ${{\mathit K}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$, ${{\mathit K}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{+}}$, ${{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}$, and ${{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{0}}$.
2  The final state flavor is determined by the kaon and pion charges where modes with ${{\mathit X}_{{{s}}}}$ = ${{\mathit K}_S^0}$ , ${{\mathit K}_S^0}$ ${{\mathit \pi}^{0}}$ or ${{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ are not used.
