Standard model appears to be flawed

Also, why would this break the SM if it did turn out be a Higgs signal? Am I missing something obvious here?

The way I understand it (from the blog post quoted below) a 150 GeV SM Higgs should have a dijet cross section of around 12fb. The CDF bump at 150 GeV is 4pb. If the CDF results are confirmed as a Higgs particle it does not conform to what the standard model predicts it should be.

If this bump really does come from a particle with mass around 150 GeV, then the first thing one might think is that this is the first hint of the Higgs boson. Indeed, we even showed above that the production of the Higgs includes diagrams that would give this particular signal when the Higgs decays into two quarks. However, one very, very interesting part of the analysis is that it does not seem like this bump could come from the standard Higgs boson!

The reason is simple: we understand the standard Higgs well enough to know that if it had a mass of 150 GeV, then we would expect an effect (a bump) that would be about three hundred times smaller. In the parlance of the field, the observed bump corresponds to a particle with a 4 picobarn dijet cross section, while a 150 GeV Higgs is expected to have a 12 femtobarn dijet cross section.
