In physics, a neutral particle is a particle with no electric charge.
Stable or long-lived neutral particles |
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 |
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]
