CHARGE ASYMMETRY IN ${{\mathit K}_{{{\ell3}}}^{0}}$ DECAYS

Such asymmetry violates $\mathit CP$. It is related to Re($\epsilon $).

$\mathit A_{\mathit L}({{\mathit e}}$) = $\lbrack{}\Gamma\mathrm {({{\mathit \pi}^{-}} {{\mathit e}^{+}} {{\mathit \nu}_{{{e}}}})}$ $−$ $\Gamma\mathrm {({{\mathit \pi}^{+}} {{\mathit e}^{-}} {{\overline{\mathit \nu}}_{{{e}}}})}$]/SUM
