SUMMARY
A neutral pion is definitively identified as a superposition of the quark-antiquark pairs u\bar{u} and d\bar{d}. This concept allows physicists to treat the neutral pion as a single particle despite its composite nature. In particle physics, the decay of neutral pions into two photons is a significant process, occurring through the anomaly in the divergence of the axial vector current, represented by a triangle diagram in Feynman diagrams. Resources such as the articles from Physical Review and Astrophysics provide further insights into these phenomena.
