$\mathit CP$ 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.
