The standard model does not include a candidate for dark matter, but it can be extended to include one or more suitable particles which can serve as the Dark Matter candidate. This paper considers an extension that includes a local U(1) symmetry, an axion particle to solve the strong CP problem, and right-handed neutrinos with appropriate mass terms to address the neutrino mass and dark matter. The axion decay constant and the right-handed neutrino masses are related to the same v.e.v.s, and the model predicts a mixed Dark Matter scenario with both axion and right handed neutrino components. The model is characterized by a reduced observational signals from each DM component.
