${{\mathit \Lambda}}$ $\mathit CP$-violating decay-rate asymmetries

This is the difference between ${{\mathit \Lambda}}$ and ${{\overline{\mathit \Lambda}}}$ decay rates to state ${{\mathit f}}$ and ${{\overline{\mathit f}}}$ divided by the sum of the rates:$
$ $\mathit A_{CP}({{\mathit f}}$) = [(B( ${{\mathit \Lambda}}$ $\rightarrow$ ${{\mathit f}}$)) $−$ (B( ${{\overline{\mathit \Lambda}}}$ $\rightarrow$ ${{\overline{\mathit f}}}$))]/Sum.

$\mathit A_{CP}({{\mathit p}}{{\mathit \mu}^{-}}{{\overline{\mathit \nu}}_{{{\mu}}}}$) in ${{\mathit \Lambda}}$ $\rightarrow$ ${{\mathit p}}{{\mathit \mu}^{-}}{{\overline{\mathit \nu}}_{{{\mu}}}}$, ${{\overline{\mathit \Lambda}}}$ $\rightarrow$ ${{\overline{\mathit p}}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$
