Eek! The Universe Is Going To Collapse! And Its All Higgs Fault!
Do not properly understand the math behind this claim at all, but I am making out my will as we speak :)

I was thinking mainly of Dark Matter, jtp, which is surely a new particle of some kind -- even if it's as simple as a right-handed neutrino or something. Also I'm reliably informed that SUSY isn't dead yet, and there are strong theoretical reasons for believing that it exists. Likelihood is that we'll need the 14 TeV run of the LHC to rule it out at least in its full current form. But it's a hard beast to kill, is SUSY, because the parameter space you have to look at is far too huge for it to be as easily ruled out as all that (I actually think this is a weakness of SUSY but I don't work on it so...).
And anyway, aside from SUSY there are goodness knows how many other theories, all of which tend to predict new particles of one form or another, and none of which have worked yet -- but we still have some 16 orders of magnitude to go until (by most people's thinking) we've reached the end of the possible scale of new stuff.

I went and did that digging I said I would at last, LG, and here's the problem: I can find either papers that explain the problem in technical language, or that don't explain it at all. There doesn't seem to be anything to bridge the gap. I might try to write one myself at some point, but for now you'll have to be content with the fuzzy hand-wavy stuff the DM wrote above.
