$\mathit CP$ VIOLATION TESTS IN ${{\mathit K}^{\pm}}$ DECAYS

$\Delta $ = ($\Gamma\mathrm {({{\mathit K}^{+}})}$ $−$ $\Gamma\mathrm {({{\mathit K}^{-}})}$) $/$ ($\Gamma\mathrm {({{\mathit K}^{+}})}$ + $\Gamma\mathrm {({{\mathit K}^{-}})}$)

$\Delta $( ${{\mathit K}^{\pm}}$ $\rightarrow$ ${{\mathit \pi}^{\pm}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$) RATE DIFFERENCE/SUM
