Abstract An extension of the standard model of electro-weak interactions by an extra abelian gauge boson is given, in which the extra gauge boson and the hypercharge gauge boson both couple to an axionic scalar in a form that leads to a Stueckelberg mass term. The theory leads to a massive Z′ whose couplings to fermions are uniquely determined and suppressed by small mixing angles. Such a Z′ could have a low mass and appear in e+e− collisions as a sharp resonance. The branching ratios into f f species, and the forward–backward asymmetry are found to have distinctive features. The model also predicts a new unit of electric charge e′=Q′e, where Q′ is, in general, irrational, in the coupling of the photon with hidden matter that is neutral under SU(2)L×U(1)Y.

Aspects of the Stueckelberg extension (2005, background): “The work presented here is a more detailed exposition and extension of of two previous publications, where the Stueckelberg extension was first achieved [5, 6, 7].”
Anomalies, anomalous U(1)'s and generalized Chern-Simons terms (2006, background): “The three-gauge-boson anomalous couplings we discuss in this paper have nontrivial consequences such as Z ′ → Z γ decays, which were not considered in the past in the context of Z ′ models [15, 18, 19 ].”
Kinetic Mixing of the Photon with Hidden U(1)s in String Phenomenology (2008, background): “The m(2)ab effects were examined recently in the framework of the “Stückelberg Z ′ model” in [12, 13, 14] whereby a massive (typically O(TeV)) boson (which may also kinetically mix with the hypercharge) couples to the standard model particles directly via such a mass mixing, allowing it to be produc”
