Interesting final comment from this short article ...
http://www.wired.com/wiredscience/20...c-anticipated/

"A 125 GeV Higgs is lighter than predicted under the simplest models and would likely require more complex theories, such as supersymmetry, which posits the existence of a heavier partner to all known particles."

Then add this from wikipedia (on the Higgs boson) ...

"The Standard Model does not predict the mass of the Higgs boson. If that mass is between 115 and 180 GeV/c2, then the Standard Model can be valid at energy scales all the way up to the Planck scale (1016 TeV). Many theorists expect new physics beyond the Standard Model to emerge at the TeV-scale, based on unsatisfactory properties of the Standard Model."

I don't understand. If the standard model doesn't predict the mass of the Higgs boson, then why is a mass of 125 GeV a problem?

Regards, Rob
