Abstract

In most cases, decays of a neutral π-meson are realized due to electromagnetic interaction. However, some rare decay modes can only be explained by weak interactions. We can assume that the decays are realized due to the electroweak interaction. Weak interaction is virtual in the decays π⁰ → 2Υ; π⁰ → Υ + e⁺ + e^–. Electrically charged particles and antiparticles born in weak virtual decays are annihilated due to electromagnetic interaction. During decays through other channels, weak interaction is real, and electromagnetic interaction has practically no effect on the decay processes. This is confirmed by the relatively long average lifetime of a neutral π meson during rare decays.
