$\mathit CP$ VIOLATION

$\mathit A_{CP}$ is defined as
${B( {{\overline{\mathit B}}} \rightarrow {{\overline{\mathit f}}})–B( {{\mathit B}} \rightarrow {{\mathit f}})\over B( {{\overline{\mathit B}}} \rightarrow {{\overline{\mathit f}}})+B( {{\mathit B}} \rightarrow {{\mathit f}})}$,
the $\mathit CP$-violation charge asymmetry of inclusive ${{\mathit B}^{\pm}}$ and ${{\mathit B}^{0}}$ decay.

1  Assumes equal production of ${{\mathit B}^{+}}$ and ${{\mathit B}^{0}}$ at the ${{\mathit \Upsilon}{(4S)}}$. Uses an opposite side lepton tag. Requires center-of-mass frame $\mathit E_{{{\mathit \gamma}}}$ $>$ 2.1 GeV.
2  Uses a fully reconstructed ${{\mathit B}}$ meson as a tag on the recoil side. Requires $\mathit E_{{{\mathit \gamma}}}$ $>$ 2.2 GeV.
3  Corresponds to $-0.27<\mathit A_{\mathit CP}<0.10$ at 90$\%$ CL.
