  "abstract": "The phases of terms of amplitude that arise from the $\\pi\\pi$ interaction are obtained by using a simple realistic model of $\\pi\\pi$ interaction via virtual $\\rho$-meson, instead of the ChPT. It is shown that the standard ChPT approach cannot reproduce the contribution of the $\\rho$-meson to the $\\pi\\pi$ interaction. It is shown that the interference between the terms of amplitude with different CP-parity appears only when the photon is polarized (linearly or circularly). Instead of measuring the linear polarization, the angular correlation between the $\\pi^{+}\\pi^{-}$ and $e^{+}e^{-}$ planes in $K_{S,L}\\to\\pi^{+}\\pi^{-}e^{+}e^{-}$ decay can be studied.",
