Multi-$Z'$ signatures of spontaneously broken local $U(1)'$ symmetry
Multi-$Z'$ signatures of spontaneously broken local $U(1)'$ symmetry
We discuss multi-$Z'$ signatures coming from decays of Higgs bosons in models with a spontaneously broken $U(1)'$ symmetry, which can be observed as "lepton jets" or multi-lepton final states depending on the mass range of new bosons. We consider anomaly-free $U(1)'$ models without introducing new fermions except for right-handed neutrinos, …
