$\mathit CP$ 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.

${{\overline{\mathit A}}}_{CP}$( ${{\mathit B}}$ $\rightarrow$ ${{\mathit K}^{*}}{{\mathit \gamma}}$) = ($\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit K}^{*+}}{{\mathit \gamma}}$) + $\mathit A_{CP}$( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{*0}}{{\mathit \gamma}}$))/2
