SUMMARY
A neutral pion can decay into two electrons and two positrons primarily through electromagnetic interactions, with a branching ratio of 3.2E-5. This decay is significantly suppressed compared to the two-photon decay mode, approximately by a factor of α², where α represents the fine structure constant. While there exists a negligible weak component mediated by Z bosons, the dominant interaction in this decay process is electromagnetic.
PREREQUISITES
