Which force is carried by the Z boson?

Quick Answer

The weak nuclear force is carried partly by the Z boson. Along with the W bosons, it mediates weak interactions.

The Full Story

The weak force has three gauge bosons: W+, W- and Z0. The Z boson mediates neutral weak interactions, while the W bosons mediate charged weak processes such as beta decay. These particles were discovered in 1983 at CERN in experiments led by the UA1 and UA2 collaborations. Their discovery confirmed the electroweak theory, which unifies electromagnetism and the weak interaction at high energies. The Z boson is a cornerstone of the Standard Model.
