$\mathit CP$ 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.

$\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{+}}$)

1  This result is obtained with an amplitude analysis of ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays, using the isobar model within the mass range 1.0 $<$ m(${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$) $<$ 1.5 GeV to describe the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{\mathit S}{\mathrm -wave}$ contribution.
2  Corresponds to 90$\%$ confidence range $-0.75<\mathit A_{\mathit CP}<0.07$.
3  Corresponds to 90$\%$ CL interval -0.25$<{{\mathit A}_{{{CP}}}}<$0.41
4  Corresponds to 90$\%$ confidence range $-0.50<\mathit A_{\mathit CP}<0.46$.
