$\mathit CP$ 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.

$\mathit A_{CP}$( ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \rho}^{0}{(1450)}}{{\mathit \pi}^{+}}$)

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  Uses amplitude analysis of ${{\mathit B}^{\pm}}$ $\rightarrow$ ${{\mathit \pi}^{\pm}}{{\mathit K}^{+}}{{\mathit K}^{-}}$ decays.
