the vacuum is crowded with Axion Higgs unification particles.
1: for Casimir energy effect reasons
2: for Lorentz polarization reasons connected to all mass effects and acceleration..
3: however, the real LHC Higgs of 124-126 GeV is a different particle.
1: The vacuum particle (called Axion-Higgs) is the mother particle of all singular strings, able to transform into all other singular strings like photons gluons electron and positron.
2: the smallest Dark matter particle is both 2x Higgs particles based on 3x magnetic monopole photon knots of North or South monopole photons.
