There’s not an awful lot to say about this as yet (and lord knows, I’m not the one to say it, in view of the fact that I haven’t even taken quantum field theory yet). If the Higgs has been found, it would seem that the standard model has been definitively confirmed. It still probably couldn’t constitute a complete particle zoo, mind you (all of that dark matter has to come from somewhere* and someone still needs to explain where all of these parameters come from, and why matter dominates over anti-matter and so on), but it will at least be an internally consistent model.
I’d just like to point one thing out though: this Scientific American article, like pretty much every other mass media report on this subject, claims that the Higgs Boson is “the origin of mass of all matter.” This is not, strictly speaking the case; the Higgs Boson gives mass only to elementary particles; composite particles (such as protons and neutrons) would still have mass due to the strong interaction.
Also, what’s really sad is that, if those FTL neutrino results pan-out, this is only going to be the second most important experimental physics discovery made this year.
*Assuming, of course, that Dark Matter actually exists.
