Is the 125 GeV Higgs boson some kind of a “almost-commutative graviton” at the electroweak scale?
The expression "almost-commutative graviton" is provocative. I use it on purpose, as some kind of a "propagandon", to ask to the physics community if the observation of only one Higgs (scalar boson) ...
