Yukawa force vs Nuclear force

What is the symmetry of the pion triplet ($\pi^{-}, \pi^{0}, \pi^{+}$)?

Why is $\pi^0 \rightarrow \gamma \rightarrow e^-e^+$ forbidden but $\pi^+\rightarrow W^+ \rightarrow e^+ \nu_e$ allowed?

Why is the decay of a neutral pion $\to$ electron-positron loop suppressed?

Quark composition of the neutral pion

What is the difference between a charged rho meson and a charged pion?

Why the pion does not get mass under Spontaneus breaking of chiral symmetry, but the quarks do?

Chiral anomaly and decay of the pion

What does it mean that the neutral pion is a mixture of quarks?
