Axion= Dark energy.string, 2x Higgs = Dark Matter magnetic monopole string knot

In Quantum FFF Theory transformer string architecture,
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.

Dark Energy = singular Axion-Higgs transformer torus strings,

Dark Matter is a compound Higgs Black Hole ( string knot) of variable sizes. based mainly 3x magnetic monopole rigid string knots

See the new physics of Rigid Transformer Strings. by Leo Vuyk. below.

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.

and: The Massless Axion-Higgs Vacuum Rigid String particle, even in Micro and Macro Dark Matter Black Hole Nuclei.
