$\mathit CP$ VIOLATION PARAMETERS

$\mathit A_{CP}$( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{*}{(2010)}^{+}}{{\mathit D}^{-}}$)

INSPIRE   PDGID:
S042AC4
$\mathit A_{CP}$ is defined as

${B( {{\overline{\mathit B}}^{0}} \rightarrow {{\overline{\mathit f}}})–B( {{\mathit B}^{0}} \rightarrow {{\mathit f}})\over B( {{\overline{\mathit B}}^{0}} \rightarrow {{\overline{\mathit f}}})+B( {{\mathit B}^{0}} \rightarrow {{\mathit f}})}$,

the $\mathit CP$-violation charge asymmetry of exclusive ${{\mathit B}^{0}}$ and ${{\overline{\mathit B}}^{0}}$ decay.
