U(1)X dark symmetry is s pontaneously broken by nonzero VEV of dark Higgs field 〈Φ〉\, generati ng the masses of dark fermions and dark photon Z′.\nThe resulting dark H iggs boson ϕ can be produced at the LHC by dark quark loop (involving 3 g eneration) and will decay into a pair of photon through charged dark fermi on loop. Its decay width can be easily ∼45 GeV due to its possible decay s into a pair of dark photon\, which is not strongly constrained by the cu rrent LHC searches pp→ϕ→Z′Z′ followed by Z′ decays into the SM fermion pairs.\nThe scalar DM can achieve thermal relic density without co nflict with direct detection bound or the invisible ϕ decay into a pair o f DM.\n\n LOCATION: URL: END:VEVENT END:VCALENDAR
