【摘要】

The existence of dark matter and the smallness of neutrino masses are two of the most compelling reasons to extend the Standard Model. In this talk we will discuss minimal scenarios, where an abelian gauge symmetry provides a framework which can incorporate dark matter, massive neutrinos and new MeV-TeV neutral gauge bosons. We will discuss the impact of light gauge bosons on low energy experiments, such as coherent elastic neutrino-nucleus scattering (CEvNS) or polarized electron scattering.
