The Z Boson
|
Symbol: Z, Z0 Group: boson, gauge boson Rest mass: 98 u Charge: 0 Mean lifetime: 3 x 10-25 sec Spin: 1 |
The Z boson, like the W boson, is a carrier of the weak interaction. It is formed at modifications of elementary particles, where only the spin, but not the charge and the particle type change. W and Z bosons are the only particles (probably together with the very weak graviton), that interact with neutrinos. Neutrinos can fission deuterium and thereby create a Z boson, which almost immediately decays again in a fermion and its antiparticle. The Z boson is about as heavy as an atom of the element technetium. |
