$\mathit CP$ 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.

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