Transition magnetic-dipole dark matter and the LZ230616 high-recoil candidate
Yuxuan He
A transition magnetic dipole connects an endothermic nuclear recoil to a delayed photon. We study this interpretation of LZ230616, the 248-keV candidate in LZ's extended-energy sea…
Probing Collapsed Dark Matter Halos with Fast Radio Bursts
Yuxuan He, Weiyang Wang, Chen Zhang +1
Observations of ultra-dense substructures in strong lensing systems challenge the standard cosmological model at small scales. Self-interacting dark matter (SIDM), as an alternativ…
Implications of the KM3NeT Ultrahigh-energy Event on Neutrino Self-interactions
Yuxuan He, Jia Liu, Xiao-Ping Wang +1
Neutrino self-interactions (SI) mediated by light bosonic particles can produce characteristic spectral dips in astrophysical neutrino fluxes, thereby altering the expected ener…
Particle Conversions Beyond the WKB Approximation and Solar-Induced Gravitational Waves from Dark Photon Dark Matter
Tengyu Ai, Yuxuan He, Jia Liu +2
We investigate the conversion of kinetic mixing dark photon dark matter into gravitational waves within the magnetic field of the Sun. Our study reveals that the WKB approximation…
Lepton flavor of four-fermion operator and fermion portal dark matter
Yuxuan He, Gang Li, Jia Liu +2
We study the ultraviolet realization of semileptonic four-fermion operator that incorporates Majorana dark matter (DM) in both lepton-flavor-conserving (LFC) and…
Constraining Ultralight Dark Matter through an Accelerated Resonant Search
Zitong Xu, Xiaolin Ma, Kai Wei +9
Experiments aimed at detecting ultralight dark matter typically rely on resonant effects, which are sensitive to the dark matter mass that matches the resonance frequency. In this…
Dark Matter Search with a Resonantly-Coupled Hybrid Spin System
Kai Wei, Zitong Xu, Yuxuan He +9
Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of dark matter (DM). Traditional axion DM experiments rely on sharp re…
Exploring Ultralight Scalar Assistance in Sterile Neutrino Dark Matter: Cold Spectrum and Unusual X/Gamma-ray Signatures
Yuxuan He, Jia Liu, Xiaolin Ma +1
We present a scalar-driven sterile neutrino production model where the interaction with the ultralight scalar field modifies the oscillation production of sterile neutrinos in the…
Unveiling Time-Varying Signals of Ultralight Bosonic Dark Matter at Collider and Beam Dump Experiments
Jinhui Guo, Yuxuan He, Jia Liu +2
The ultralight boson represents a promising dark matter candidate exhibiting unique wave-like behaviors. These properties could transfer to the dark mediator, such as the kinetic m…
Heavy long-lived coannihilation partner from inelastic Dark Matter model and its signatures at the LHC
Jinhui Guo, Yuxuan He, Jia Liu +1
The coannihilation mechanism is a well-motivated alternative to the simple thermal freeze-out mechanism, where the dark matter relic density can be obtained through the coannihilat…
