Abstract

We examine theoretical features of U (1) X extensions of the Standard Model whose quantum anomalies are canceled per generation. Similarly to other versions, the theory consists of a Two-Higgs-Doublet Model plus a scalar singlet embedded into the SM ⊗ U (1)X gauge group, and introduces small modifications to the Z -boson interactions. These changes can be minimized by exclusively charging right-handed fermions under the new Abelian symmetry, and are compensated by the neutral X -boson exchange. Non- universality of fermion couplings can also be achieved by requiring one single X -charged family. In general, X gauge bosons can be separated into A′ and Z′ subsets, distinguished by the presence of axial-vector components in the Z′ exchange. A′ physics, in particular the dark photons case, is commonly simpler to constrain and therefore favored by experimental tests. Finally, the model can be UV completed both by stable χ fermions or by right-handed neutrinos. The prior case may provide cold WIMPs in the theory.
