Neutral particle

In physics, a neutral particle is a particle with no electric charge.

Stable or long-lived neutral particles change

Long-lived neutral particles do not decay for a very long time. Examples of such particles include photons,^{[PDG 1]} neutrons,^{[PDG 2]} and neutrinos.^{[PDG 3]}

Other neutral particles change

Other neutral particles are very short-lived. They decay before they can be detected by a particle detector. They have been observed only indirectly, such as tracks of ionized particles in a particle accelerator. They include:

Z bosons^{[PDG 4]}
Dozens of heavy neutral hadrons:
- Neutral mesons such as the pion^{[PDG 5]} and kaon^{[PDG 6]}
- The neutral Delta baryon,^{[PDG 7]} and other neutral baryons, such as the xi baryon^{[PDG 8]} and lambda baryon^{[PDG 9]}
