- You mean "give mass to the ordinary fermions," don't you?
-
- People are still messing around over here with somehow doing that
- with extended technicolor bosons, with a "sideways" vertex that
- changes a fermion to a technifermion. To me, it seems that
- the most realistic models are incredibly baroque, and it's
- disquieting to think that the whole motivation is to solve the
- gauge hierarchy problem so that the buck can be passed to some
- truly humongous GUT gauge group up at 10^15 GeV.
