Yes, I think I was wondering if maybe all mass can be seen as arising from massless particles and interactions, within the subatomic particles, a new layer sotospeak (like preons). I'm assuming that would require a really big particle accelerator to blast apart quarks and leptons.
If something like that were true, that quarks and leptons had internal structure that was massless, therefore ALL mass was arising from nonmassive energy. What would this mean for the Higgs? Would it no longer be necessary?

I was betting against it until we actually got results, now I need to figure out why that coupling should be there... The only argument I can think of is a type of naturalness argument where dimensionless constants are more desirable than constants with dimension (still fails miserably when those dimensionless constants are <<1)

Edit: plus, you need SUSY or something to make the Higgs mass not sensitive to whatever this high scale stuff is...

Massive fermions ARE renormalizable, that's why I don't get why the Higgs is needed to "give" them mass. Unlike the W and Z fermions can have intrinsic mass!
