Description
In this talk, we discuss minimal spontaneously broken local $U(1)’$ models. The candidates of $U(1)’$ symmetry are $U(1)_{B-L}$, $U(1)_{L_i - L_j}$ and hidden $U(1)$ so that the SM Higgs field is not charged under $U(1)’$. When $U(1)’$ gauge symmetry is spontaneously broken we have both new gauge and scalar bosons. We show these models can provide multi-Z’ signatures at the LHC via scalar boson production and decays, taking into account relevant constraints from Z’ and new scalar boson search in various experiments.
