I know that symmetry breaking in the Electroweak theory does a great job of explaining the existence and masses of the W and Z bosons, but I'm a little confused about the role of the fourth particle required by the theory. Some sources say that the fourth particle is just the photon, and that it remains massless as a gauge boson should (unlike the W and Z bosons). Other sources indicate that the fourth particle is the boson of the Higgs field itself, giving everyone's favorite latest discovered particle. So which scenario is it?
