$\mathit CP$ 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.
