Well... we kind of don't expect that we've found all the particles that are out there. Primarily, but not
exclusively, there's the matter of dark matter. Current physics investigations are largely about ruling out
what kinds of new particles probably don't exist. Edit: Analogy: Imagine you're in Renaissance Europe.
You know the size of the Earth and you know pretty much all of Eurasia and Africa, at least rough
outlines. And you know like 2/3 of the earth's longitude still hasn't been explored. You can send off some
ships and hope you find some land somewhere in that remaining space. You're not certain you'll find
anything, and even if your first ships come back empty, you now know where land isn't. Unless of course,
you're Christopher Columbus and completely deluded about the size of the Earth and think that we've
already found all there is to find. So testability is pretty reasonable, it would just require precision
measurements of the Higgs and its couplings and possible couplings to new particles. There's a chance,
but not a guarantee, that the ILC would be able to make precision Higgs measurements. Mostly, I like it
because seesaw mechanisms are pretty well established in the literature and it wouldn't be too crazy to
imagine a Higgs interaction with some other thing that would create such an effect to create the right
amount of background vacuum energy.
