Direct detection of boosted dark matter in two component dark matter scenario
Abstract
We investigate the detection of boosted dark matter in a two component dark matter model with the hidden gauge $U(1)_D$ symmetry. The model introduces heavy and light fermionic dark matter components, where the heavy dark matter annihilation in the Galactic center boosts the light dark matter. Directional direct detection experiments, such as NEWSdm, are suitable for testing the boosted scenario by focusing on signals from the Galactic center. We found that the expected event rate could reach up to O(10) events per year per 5 kg of the detector material.
