Faitau le fuaiupu i lalo ma tali le fesili i le gagana lava lea e tasi e pei o le fuaiupu: Fuaiupu: Electroweak unification is a broken symmetry: o le electromagnetic and weak forces appear distinct at low energies because the particles carrying the weak force, the W and Z bosons, have non-zero masses of 80.4 GeV/c2 and 91.2 GeV/c2, whereas the photon, which carries the electromagnetic force, is massless. I le maualuga o le malosi e mafai ona faigofie ona fatuina Ws ma Zs ma o le natura tuufaatasia o le malosi e manino. Fesili: O le a le electroweak unification?
