Out of curiosity: what are you referring to?

#6This article conflates all sorts of loosely connected ideas and buzzwords without really giving a solid explanation of any of them (least of all this new result). A more focused look at this particular (but quite preliminary) result can be found at

From the sound of it, many of the details won't become available until a seminar tomorrow. (Nevertheless, it sounds like this really will constrain many forms of "new physics" by quite a bit.)

#8can anyone confirm my understanding of the basic physics here?
they are observing a transition from one particle to another that involves a process whose probability depends on "all particles" in some weird sense, because it includes particle-antiparticle pairs (so is affected by vacuum fluctuations?).
because of this, they have a weird situation where an experimental result depends on all possible particles (below some energy cutoff i guess).
and that is why it's a good test for standard model v super-symmetry. because super-symmetry (to be symmetric) predicts a bunch more particles. and if those are real, we would see something different.
i am not sure where i got this from, but it seemed to be implied by one of the links here...

#9I would just like to take a moment here to draw attention to the fact that the planned Superconducting Supercollider would have been even more capable at probing supersymmetry than the LHC and had it not been cancelled it would have been operating for well over a decade by now.

"decay", not "delay"
