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…
Associated Production of Neutrino and Dark Fermion at Future Lepton Colliders
Shao-Feng Ge, Kai Ma, Xiao-Dong Ma +1
Fermionic dark matter can be pairly produced and hence searched with missing energy at colliders. We extend such probe to the associated production of a neutrino and a dark sector…
Right-Handed Neutrino Dark Matter with Forbidden Annihilation
Yu Cheng, Shao-Feng Ge, Jie Sheng +1
The seesaw mechanism with three right-handed neutrinos has one as a well-motivated dark matter candidate if stable and the other two can explain baryon asymmetry via the thermal le…
Forbidden Dark Matter Combusted Around Supermassive Black Hole
Yu Cheng, Shao-Feng Ge, Xiao-Gang He +1
The forbidden dark matter cannot annihilate into a pair of heavier partners, either SM particles or its partners in the dark sector, at the late stage of cosmological evolution by…
Revisiting the Fermionic Dark Matter Absorption on Electron Target
Shao-Feng Ge, Xiao-Gang He, Xiao-Dong Ma +1
We perform a systematic study of the fermionic DM absorption interactions on electron target in the context of effective field theory. The fermionic DM absorption is not just sensi…
Solar Active-Sterile Neutrino Conversion with Atomic Effects at Dark Matter Direct Detection Experiments
Shao-Feng Ge, Pedro Pasquini, Jie Sheng
The recent XENON1T excess can be explained by the solar active-sterile neutrino conversion with bound electrons via light mediator. Nevertheless, the atomic effects are usually omi…
Solar Neutrino Scattering with Electron into Massive Sterile Neutrino
Shao-Feng Ge, Pedro Pasquini, Jie Sheng
The recent Xenon1T excess can be explained by solar neutrino scattering with electron via a light mediator, either scalar or vector, in addition to many other explanations from the…
