W and Z bosons

In physics, the W and Z bosons are the elementary particles that mediate the weak nuclear force. Their discovery at CERN in 1983 has been heralded as a major success for the Standard Model of particle physics.

The W particle is named after the weak nuclear force. The Z particle was semi-humourously given its name because it was said to be the last particle to need discovery. Another explanation is that the Z particle derives its name from the fact that it has zero electric charge.
