Description
Additional gauge interactions are ubiquitous in well motivated extensions of the Standard Model (SM); a particularly simple example is that of an extra $U(1)$ gauge group. In this work, we study the case in which there are simultaneously both kinetic mixing and mass mixing (arising from the Higgs sector) of this extra $U(1)$ into the SM. We show that the additional gauge boson, called the 'dark $Z$', can potentially be discovered at future $e^+ e^-$ colliders (e.g. the ILC). In addition, we demonstrate how the ILC can perform precision studies on the dark $Z$'s couplings with SM fermions.
