Quark confinement and meson confinement

So you say one should throw away all QCD results based on T³

I never said that. One should view the QCD results based on the torus as results that may need modification in the infinite-volume limit, at least those modifications that are already needed in case of QED.

There are of course known differences regarding topology, large gauge transformations / winding number, gauge field zero modes etc. It would not be a disaster to add some more topics to that list.

But: as long as we do not know how the topology of the universe looks like, this is academic; I can't believe (and I hope that I am not completely wrong) that the cosmological constant doe not affect the QCD spectrum :-)

You have here a double negation. Did you intend that not not x = x? I'd be surprised...

For the purposes here on earth, the universe can be regarded as being topologically
flat, and gravitation can be treated as an external field. Under these conditions, I believe that both QED and the standard model or its variants are consistent.

Thanks for correcting me: As long as we do not know how the topology of the universe looks like, this is academic; I can't believe that the cosmological constant does affect the QCD spectrum.
