Figure 1. Portals to hidden sectors. The diagram represents the energies of possible hidden-sector states in relation to those of the standard model. Colored arrows indicate possible transitions between states. At the Large Hadron Collider hidden-sector states can be created by means of the production and decay of heavy mediators (a) exotic decays of the Higgs boson (b) or small direct couplings (c). Once produced the states decay through the same portals. Hidden-sector states have long lifetimes because the direct couplings are small or because energy must be borrowed courtesy of the Heisenberg uncertainty principle to excite the intermediate mediator or Higgs boson. Why is there something rather than nothing? Its a question so basic and so vast in scope that
