Quantum Haplodynamics, Dark Matter and Dark Energy
  In quantum haplodynamics (QHD) the weak bosons, quarks and leptons are bound
states of fundamental constituents, denoted as haplons. The confinement scale
of the associated gauge group SU(2)_h is of the order of $\Lambda_h\simeq 0.3$
TeV. One scalar state has zero haplon number and is the resonance observed at
the LHC. In addition, there exist new bound states of haplons with no
counterpart in the SM, having a mass of the order of 0.5 TeV up to a few TeV.
In particular, a neutral scalar state with haplon number 4 is stable and can
provide the dark matter in the universe. The QHD, QCD and QED couplings can
unify at the Planck scale. If this scale changes slowly with cosmic time, all
of the fundamental couplings, the masses of the nucleons and of the DM
particles, including the cosmological term (or vacuum energy density), will
evolve with time. This could explain the dark energy of the universe.
