$\mathit CP$ VIOLATION PARAMETERS

$\Delta \mathit S_{{{\mathit a}_{{{1}}}} {{\mathit \pi}}}$ ( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit a}_{{{1}}}{(1260)}^{+}}{{\mathit \pi}^{-}}$)

INSPIRE   PDGID:
S042SDA
$\Delta \mathit S_{{{\mathit a}_{{{1}}}} {{\mathit \pi}}}$ is related to the strong phase difference between the amplitudes contributing to ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit a}_{{{1}}}}{{\mathit \pi}}$ decays.
