The Higgs boson, the only particle missing in the standard model, is awaited to be discovered at LHC for establishing the unification scenario of electroweak interactions. There may be supersymmetry and extra-dimensional space behind them. The ultimate unification of all interactions including gravity is achieved in superstring theory.

  I discovered the Hosotani mechanism in 1983 which led to the gauge-Higgs unification. There the Higgs boson is unified with gauge fields in higher dimensions, in which Higgs bosons become absolutely stable and constitute the dark matter in the universe.
