Dark photons from the center of the Earth: Smoking-gun signals of dark matter
Dark photons from the center of the Earth: Smoking-gun signals of dark matter
Dark matter may be charged under dark electromagnetism with a dark photon that kinetically mixes with the Standard Model photon. In this framework, dark matter will collect at the center of the Earth and annihilate into dark photons, which may reach the surface of the Earth and decay into observable …
