Elementary particles; gauge bosons that mediate the weak interaction.
1
And anyway, what about the W and Z bosons?
2
The discovery of higher-mass W and Z bosons would shed important new light on these interactions.
3
These are heavier versions of the W and Z bosons, which are responsible for weak interactions.
4
The reason for the difference is the mass of the W and Z bosons, which carry the weak force.
5
"The W and Z bosons?" she repeated.
