$\mathit CP$ 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.

$\mathit A_{CP}({{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit f}_{{{2}}}{(1270)}}{{\mathit K}^{+}}$)
