Is it the intensity of the magnetic dipole moment (spin 2 more intense)? What does this have to do with repulsion and attraction? I'm curious and interested...

My second question is, do gluons have mass? Afterall the strong force is short ranged... yet you only ever hear of W and Z particles as having mass.

Lastly, in quantum physics....
Is it safe to say that the weak force is infinitely ranged, but the reason that its influence seems to be so limited to short distances is because the probability of interaction with a W or Z particle becomes diminishingly small very rapidly as distance is increased? In other words... the weak force is infinitely ranged, but the chance of "feeling" it is basically negligible at distance scales greater than an atomic nucleus. Afterall, the wave function of any particle is assigned a nonzero value throughout the whole universe according to QM correct? So too, would be the wave functions of weak bosons.
