This mass generation for the photon gives rise to the peculiar features of superconductors, e.g., they have absolutely no electrical resistance to current flow. In fact, the forces that are mediated by the quantum exchange of W' s between other particles are exactly the weak forces that Fermi was trying to understand 60 years ago . Indeed, the weak forces are weak because the W and Z are heavy. We conceive of the same kind of quantum effect as in a superconductor acting everywhere throughout the Universe to give the W's and Z their masses, in analogy to the way that the superconductor gives the photon a mass. The Fermi scale is the direct quantitative measure of this phenomenon.
Condensation is only vaguely something like the formation of dew on a lawn in the cold early fall.
This is a very feeble coupling strength, so the electron is very low mass particle. The W has a mass of about 80 GeV and the Z a mass of about 90 GeV and these are presently being measured to very high precision. So, knowing e, W and G F , we can predict M W and M Z . We don't know. We know there must be something there that either really is a Higgs field, or that imitates one in a very faithful way.
