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…
A Search for Light Fermionic Dark Matter Absorption on Electrons in PandaX-4T
Dan Zhang, Abdusalam Abdukerim, Zihao Bo +89
We report a search on a sub-MeV fermionic dark matter absorbed by electrons with an outgoing active neutrino using the 0.63 tonne-year exposure collected by PandaX-4T liquid xenon…
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…
