$\mathit CP$ 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.
