Description
Long-range forces in the dark sector can modify possible detection signatures of dark matter (DM). In this talk, I will discuss the scenario whereby 100% of the DM passing through the Earth is boosted due to new attractive long-range forces. This results in two main improvements in detection capabilities: 1) the large boost allows for detectable signatures of DM well below a GeV at large-volume neutrino detectors, such as DUNE, Super-K, Hyper-K, and JUNO, as possible DM detectors, and 2) the flux at the Earth’s surface is enhanced by a focusing effect. In particular, the latter also leads to a significant anisotropy in the signal, with the DM flux being predominantly vertical at the Earth’s surface. I will show the prospective sensitivity of the above experiments to this scenario, and discuss the implications for different models with long-range forces.
