$\mathit CP$ VIOLATION

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

$\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \psi}{(2S)}}{{\mathit K}^{+}}$)

1  Uses ${{\mathit \psi}{(2S)}}$ $\rightarrow$ ${{\mathit p}}{{\overline{\mathit p}}}$ decays.
2  Uses $\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit K}^{+}}$) = $0.001$ $\pm0.007$ to extract production asymmetry.
3  A $+0.3\%$ correction is applied due to a slightly higher reconstruction efficiency for the positive kaons.
