As I understand it in a normal superconductor electromagnetic fields are extinguished by opposing fields produced by induced superconducting currents. This causes photons to only penetrate a short distance into a superconductor. I understand that one can imagine the Higgs field as a kind of superconductor in normal space. Thus by analogy the weak nuclear force fields are extingushed by opposing weak fields produced by Higgs currents. Thus the weak force particles, the Z, W+, W- bosons only travel over short distances before they are extinguished. Does this mean that it is more correct to say that the weak force bosons are short ranged rather than to say they acquire mass or are the two statements equivalent?
