$\mathit P$ AND $\mathit CP$ VIOLATION ASYMMETRIES

a$_{CP}$( ${{\mathit \Xi}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ )

INSPIRE   PDGID:

S070A02

Observable calculated as half of the difference between triple products for ${{\mathit \Xi}_{{b}}^{0}}$ and ${{\overline{\mathit \Xi}}_{{b}}^{0}}$, which is sensitive to $\mathit CP$ violation.
