$\mathit CP$ 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.

$\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\overline{\mathit p}}}{{\mathit K}^{+}}$)
