Multi-component dark matter and Galactic 511 keV γ-ray emission
Abstract We study multi-component dark matter scenarios and the Galactic 511 keV γ-ray emission line signal in the framework of a local, dark U(1) D extension of the Standard Model. A light vector dark matter particle associated with the dark U(1) D may decay and annihilate to electron-positron pair...
