Degeneracy Enhancement of Neutron-Antineutron Oscillation in Neutron Star
Xuan-Ye Fu, Shao-Feng Ge, Zi-Yang Guo +1
We explore the fermion oscillation in a degenerate environment. The direct consequence is introducing a Pauli blocking factor , where is the phase space distribution…
Disentangle Neutrino Electromagnetic Properties with Atomic Radiative Pair Emission
Shao-Feng Ge, Pedro Pasquini
We elaborate the possibility of using the atomic radiative emission of neutrino pair (RENP) to probe the neutrino electromagnetic properties, including magnetic and electric dipole…
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…
Unique Probe of Neutrino Electromagnetic Moments with Radiative Pair Emission
Shao-Feng Ge, Pedro Pasquini
The neutrino magnetic and electric moments are zero at tree level but can arise in radiative corrections. Any deviation from the Standard Model prediction would provide another ind…

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…
Snowmass2021 Cosmic Frontier: The landscape of low-threshold dark matter direct detection in the next decade
Rouven Essig, Graham K. Giovanetti, Noah Kurinsky +90
The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in the past few years. We summarize the science case for these searches, the recent progress,…

We explore the possibility of using the recently proposed THEIA detector to measure the oscillation with neutrinos from a muon decay at rest (DAR)…
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…

John Ellis, Shao-Feng Ge, Kai Ma
We explore the experimental sensitivities of measuring the process at the LHC to the dimension-8 quartic couplings of gluon pairs to the boson and photon,…
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…

Shao-Feng Ge, Pedro Pasquini
We propose a new possibility of using the coherently enhanced neutrino pair emission to probe light-mediator interactions between electron and neutrinos. With typical momentum tran…

We demonstrate how probes of CP-violating observables in Higgs di-tau decays at prospective future lepton colliders could provide a test of weak scale baryogenesis with significant…
Parity Violation and Chiral Oscillation of Cosmological Relic Neutrinos
Shao-Feng Ge, Pedro Pasquini
The conventional derivation of neutrino oscillation treats neutrino mass eigenstate as plane wave with an overall evolution phase. Nevertheless, due to the intrinsic parity-violati…
Supernova-scope for the Direct Search of Supernova Axions

If a supernova explosion occurs within a few hundred parsecs from the Earth, a huge number of axions, in addition to neutrinos, may arrive at the Earth. In this paper, we discuss i…
