$\mathit CP$ 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.

$\Delta \mathit A_{CP}({{\mathit B}}$ $\rightarrow$ ${{\mathit K}^{*}}{{\mathit \gamma}}$) = $\mathit A_{CP}({{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit K}^{*+}}{{\mathit \gamma}}$) $−$ $\mathit A_{CP}({{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{*0}}{{\mathit \gamma}}$)
