Abstract
The U(1) D gauge sector containing one dark Higgs boson h D and one dark photon γ D may be explored through the decays of the 126 GeV particle discovered at the Large Hadron Collider (LHC), assumed here as the heavier mass eigenstate h 1 in the mixing of the standard model h with h D . The various decays of h 1 to γ D γ D , h 2 h 2, h 2 γ D γ D and h 2 h 2 h 2 would yield multilepton final states through the mixing of γ D with the photon and the decay h 2 → γ D γ D , where h 2 is the lighter dark Higgs. Future searches for signals of multilepton jets at the LHC may reveal the existence of this possible dark sector governed simply by the original Abelian Higgs model.
