A pion is one of the light pseudoscalar mesons produced by chiral symmetry breaking in quantum chromodynamics. The charge states are , and .
Conceptually the simplest mesons. All of them have neutral color charge:
- charged: down + anti-up or up + anti-down, therefore with net electrical charge electron charge
- neutral: down + anti-down or up + anti-up, therefore with net electrical charge 0
