$\mathit A_{CP}$ is defined as

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

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