$\mathit CP$ 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.

$\mathit A_{ADS}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit D}^{*}}$( ${{\mathit D}}{{\mathit \gamma}}$) ${{\mathit \pi}^{+}}$ )

${{\mathit A}_{{ADS}}}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit D}^{*}}$( ${{\mathit D}}{{\mathit \gamma}}$) ${{\mathit \pi}^{+}}$ ) = (R${}^{-}_{{{\mathit \pi}}}$ $−$ R${}^{+}_{{{\mathit \pi}}}$) $/$ (R${}^{-}_{{{\mathit \pi}}}$ + R${}^{+}_{{{\mathit \pi}}}$), where R${}^{-}_{{{\mathit \pi}}}$ = $\Gamma $( ${{\mathit B}^{-}}$ $\rightarrow$ ( ${{\mathit \gamma}}$ [ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$ ]$_{D}$ )$_{{{\mathit D}^{*}}}$ ${{\mathit \pi}^{-}}$ ) $/$ $\Gamma $( ${{\mathit B}^{-}}$ $\rightarrow$ ( ${{\mathit \gamma}}$ [ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}$ ]$_{D}$ )$_{{{\mathit D}^{*}}}$ ${{\mathit \pi}^{-}}$ ) and R${}^{+}_{{{\mathit \pi}}}$ = $\Gamma $( ${{\mathit B}^{+}}$ $\rightarrow$ ( ${{\mathit \gamma}}$ [ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}$ ]$_{D})_{{{\mathit D}^{*}}}$ ${{\mathit \pi}^{+}}$ ) $/$ $\Gamma $( ${{\mathit B}^{+}}$ $\rightarrow$ ( ${{\mathit \gamma}}$ [ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$ ]$_{D})_{{{\mathit D}^{*}}}$ ${{\mathit \pi}^{+}}$ )
