We consider a dark sector with SU(3)C×U(1)Y×U(1)X and three families of dark fermions that are chiral under dark U(1)X gauge symmetry, whereas scalar dark matter X is the SM singlet. U(1)X dark symmetry is spontaneously broken by nonzero VEV of dark Higgs field ⟨Φ⟩, generating the masses of dark fermions and dark photon Z′. The resulting dark Higgs boson ϕ can be produced at the LHC by dark...
