Abstract:
In this talk we will discuss a recent study of a vector low-mass
dark matter candidate W', accompanied by a dark photon A' and a dark Z' in the
context of a simplified gauged two-Higgs-doublet model.  The parameter space
of the model (allowed by experimental and theoretical constraints) indicates
that a dark Z' can be important for annihilation of dark matter while a dark
photon is crucial for direct detection.  Furthermore, the currently allowed
parameter space can be probed in the near future by sub-GeV dark matter
experiments like CDEX, NEWS-G and SuperCDMS.
