Implications of Higgs Particle on Physics

[Tanelorn]

Could someone please summarize what are the implications to Physics if the Higgs particle is

1. Discovered roughly as predicted.
2. Not detected at CERN at these energy levels.
3. Never detected.


Would I be correct in saying that the Higgs particle is a predicted particle in the standard model and therefore most Physicists expect to find it and it would be pleased to find it to add further evidence for the standard model?

Depends on what you mean by "Higgs particle", and what you mean by "most". Greater than 50 percent?

Something in the TeV energy range must save the standard model from itself - since the W is a massive vector boson, W-W scattering will violate unitarity without the Higgs particle or something like it. It doesn't have to be the plain vanilla Higgs particle, there are plenty of alternatives. Supersymmetry for example (MSSM) predicts five Higgs particles.

I think most physicists expect to be surprised.
