As such the Z o, more than the W particle, is an indicator that the theorists are on the right track.

A theory with only charged W particles turns out to have infinite quantities that arise in calculating certain effects.

The parity-violation experiments, however, do not prove the existence of the charged W particles.

It is called the "W particle" and as yet the report is a tentative one.

The term describes the interaction between the three W particles and the B particle.

A stream of W particles is involved and they mediate the weak interaction.

However, even simple estimates for the W particle suggest that it should weigh in at something like 30 times the proton's mass.

At first sight this energy seems sufficient to produce 'free' W particles copiously.

Are these events, like the one shown in Figure 2, really the footprint of the long-awaited W particle?

The muon can, for example, fleetingly become a W particle and a neutrino.
