Conceptually the simplest <mesons>. All of them have neutral <color charge>:
* charged: down + anti-up or up + anti-down, therefore with net electrical charge $\pm1$ <electron charge>
* neutral: down + anti-down or up + anti-up, therefore with net electrical charge 0

A pion is one of the light pseudoscalar mesons produced by chiral symmetry breaking in quantum chromodynamics. The charge states are $\pi^+$, $\pi^0$ and $\pi^-$.
