Definition: The Z boson is a type of fundamental particle that, along with the W boson, mediates the weak nuclear force. It is a called a boson because it has a quantum spin with an integer value. The Z boson has the following properties:
- 0 electrical charge; it is electrically neutral
- The anti-particle of a Z boson is another Z boson.
- Mass = 91.1876 GeV/c2
- Particle spin = 1
Also Known As: Z0 boson
