## Main Question or Discussion Point

reading the light-heart book of Aitchison, "an informal intro...", we see that the problem with mass terms in the electroweak bosons is not that they spoil gauge invariance, but that they spoil gauge invariance in a way that it is not recovered when their mass goes to zero.

After one has been forced to introduce these auxiliary scalar fields, it seems that they only way to organize them is via the Higgs field.

Now, in susy, the scalar fields are not an extra. They come included, via the susy generators, in any massive vector multiplet. So they natural... do they need to come from a higgs, at all. I mean, it seems that the limit M--->0 works perfectly in this case, just separating the massive multiplet in a massless vector plus a massless chiral.
