- That's not the way I understand it. If you take the SM by itself, there
- are intrinsic problems which are guaranteed to arise at sufficiently high
- energy. In loose terms, the Higgs particle behaves badly at high energy,
- causing "violation of unitarity," i.e., probabilities for certain processes
- are predicted to be greater than unity. If I remember correctly, these
- problems arise with quadratic Higgs self-couplings and longitudinal W-W
- scattering.
-
- Although we have not yet probed the energy scale at which this arises,
- so that in the strict sense you are correct that there is no experimental
- evidence for SS, we know that the problems are coming and that SS is
- a way out, which offers additional theoretical appeal on other fronts
- as well.
-
- I think that it would be fair to consider these problems with the SM
- as some "theoretical" evidence for SS or some other theory which is
- mathematically similar.
