$\mathit CP$ VIOLATION

$\mathit A_{CP}$ is defined as
$\mathit A_{CP}$ = ${B({{\mathit \Lambda}_{{{b}}}^{0}} \rightarrow {{\mathit f}}) – B({{\overline{\mathit \Lambda}}_{{{b}}}^{0}} \rightarrow {{\overline{\mathit f}}})\over B({{\mathit \Lambda}_{{{b}}}^{0}} \rightarrow {{\mathit f}}) + B({{\overline{\mathit \Lambda}}_{{{b}}}^{0}} \rightarrow {{\overline{\mathit f}}})}$,
the $\mathit CP$-violation asymmetry of exclusive ${{\mathit \Lambda}_{{{b}}}^{0}}$ and ${{\overline{\mathit \Lambda}}_{{{b}}}^{0}}$ decay.

$\mathit A_{CP}({{\mathit \Lambda}_{{{b}}}}$ $\rightarrow$ ${{\mathit D}}{{\mathit p}}{{\mathit K}^{-}}$)
