a (rather weak!!) argument [from BICEP2 ] slightly in favor of supersymmetry...
'' One last one which is the weakest of the set… In a recent article, I pointed out that if the Higgs particle discovered at the LHC turns out to be of the simplest possible type — a “Standard Model Higgs” — then because this is “unnatural” (in the sense of “highly non-generic”) it might call into question fundamental conceptual issues, perhaps even the whole framework of quantum field theory. But BICEP2′s measurement would seem to support the framework of quantum field theory in a world of three smooth spatial dimensions up to very high scales and very short distances, so that line of thinking would be disfavored. (IF… IF…) Of course, measurements of the Higgs particle are still in the early days — at this point we can only say the Higgs particle is roughly “Standard-Model-like” in type — and maybe the Higgs will turn out to be more complex, or other new particles will show up at the LHC, possibly rendering the discussion moot. But (for reasons I outlined in my Santa Barbara talk two weeks ago) having only the Standard Model, with the Higgs field turned on just a little, plus quantum gravity and an inflaton field (and plus something to explain dark matter and neutrino masses) would pose many grave conceptual problems, ones that anthropic reasoning would not address. [Experts: Anthropic reasoning can be used to argue why the cosmological constant might be small; it can be used to argue why there is a hierarchy between the Planck mass and the proton and electron masses; but it cannot easily be used, without huge and problematic assumptions, to argue why one would find just the Standard Model at the LHC, with one light scalar Higgs field and nothing else new.] So I would tend to see the BICEP2 result (IF… IF…) as a (rather weak!!) argument slightly in favor of supersymmetry and grand unification, with supersymmetry just a little out of reach of the LHC for some reason, or modified in some way to make it harder to observe than expected. [Experts: "mini-split" supersymmetry, which preserves quantum field theory, with unification of coupling constants at the grand unified energy scale, starts to look better than something more radical.]'''
Hope so!!
In that case, please be so kind as cf. associate SUSY with (very) early universe cosmology.
