Freeze-in sterile neutrino dark matter in a feebly gauged B − L model

Abstract We consider the gauged U(1) B−L model and examine the situation where the sterile neutrino is a dark matter candidate produced by the freeze-in mechanism. In our model, the dark matter N is mainly produced by the decay of a U(1) B−L breaking scalar boson ϕ. We point out that the on-shell pr...
