$\mathit CP$ VIOLATION PARAMETERS

$\Delta \mathit S_{ {{\mathit \rho}} {{\mathit \pi}} }$ ( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit \rho}^{+}}{{\mathit \pi}^{-}}$ )

INSPIRE   PDGID:
S042SDT
$\Delta \mathit S_{ {{\mathit \rho}} {{\mathit \pi}} }$ is related to the strong phase difference between the amplitudes contributing to ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit \rho}^{+}}{{\mathit \pi}^{-}}$ .
