Relativistic Atomic Effects of Dark Matter Electron Scattering
Shao-Feng Ge, Jie Sheng, Chuan-Yang Xing
The dark matter scattering with atomic bound electrons is a crucial avenue for exploring the sub-GeV mass range. The commonly used factorization, where atomic effects are encoded i…

Nuclear Production and Analytic Attenuation of Energetic MeV Solar Dark Matter
Shao-Feng Ge, Jie Sheng, Chen Xia +1
We propose a solar production mechanism of MeV dark matter to overcome the energy threshold in direct detection experiments. In particular, the proton and deuteron fussion to ${}^3…

Dark Matter Annihilation via Breit-Wigner Enhancement with Heavier Mediator
Yu Cheng, Shao-Feng Ge, Jie Sheng +1
We propose a new scenario that both the dark matter freeze-out in the early Universe and its possible annihilation for indirect detection around a supermassive black hole are enhan…
