Sterile neutrino dark matter in a U(1) extension of the standard model
  We explore the possibilities of dark matter production in a U(1) extension of
the standard model, also called the super-weak model. The freeze-in and
freeze-out mechanisms are described in detail, assuming the lightest sterile
neutrino in the model as the dark matter candidate. In both scenarios we
present the favoured parameter space on the plane of super-weak coupling versus
the new gauge boson mass. We discuss the experimental constraints limiting each
case and outline possibilities of detection.
