##\pi^\pm## are mutual particle-antiparticle pairs, while ##\pi^0## is it's own antiparticle. All has a spin of 0.
In any annihilation reaction of a particle ##x##, the equation is
$$x+\bar{x}\to \gamma+\gamma$$
Photons have no charge but a spin 1. I can see charges are conserved but spin is not since the total spin before the reaction is 0 while after the reaction is 2. Is there a solution to this or am I just wrong?
Sorry the LaTeX here behaves differently from the one on my computer.
