text: The particles describing the interaction of the electromagnetic force are massless photons, the Weak force is described through three gauge bosons, the W +, the W¡, and the Z0, which carry the electrical charges represented by their super- scripts and have non-zero mass, and the strong force is mediated through the exchange of massless gluons, of which there are eight.
