TeV Higgsino Dark Matter from LZ Nuclear Recoil to Fermi-LAT Gamma Rays
Lei Wu, Yang Zhang, Bin Zhu
The excess of high-energy nuclear recoils, which was recently reported by the LUX-ZEPLIN (LZ) experiment, together with the Fermi-LAT Galactic-Center preference, suggests new physi…
Neutrino lines and photon continua from cascade dark matter decay
Jun Guo, Shi-ying Zhao, Bin Zhu
We investigate the two-body decay of fermionic dark matter, , where the light mediator subsequently decays into photons. We consider two benchmark model…
Search for Ultralight Dark Matter with Quantum Magnetometry in the Earth's Cavity
Ariel Arza, Yuanlin Gong, Jun Guo +12
Ultralight dark matter candidates, such as axions and dark photons, are leading dark matter candidates. They may couple feebly to photons, sourcing oscillating electromagnetic sign…
Geomagnetic constraints on Millicharged Dark Matter
Ariel Arza, Yuanlin Gong, Jing Shu +3
Millicharged particles are well-motivated dark matter candidates arising in many extensions of the Standard Model. We show that, despite their tiny coupling to photons, milli…
Halo-dependent Anharmonic Effects in Collective Excitation for Light Dark Matter Direct Detection
Jun Guo, Lei Wu, Bin Zhu
Phonon, the collective excitation of lattice vibration in the crystal, has been put forward as a means to search for light dark matter. However, the accurate modeling of the multi-…
Direct detection of Higgs portal for light self-interacting dark matter
Wu-Long Xu, Jin Min Yang, Bin Zhu
Self-interacting dark matter (SIDM) can address the small-scale anomalies and previous researches focused on such a SIDM heavier than GeV, for which the self-scattering cross-secti…
Probing Ultralight Primordial Black Hole Dark Matter with XMM Telescopes
Jun Guo, Qiang Yuan, Bin Zhu
Primordial black holes (PBHs), originating from the gravitational collapse of large overdensities in the early Universe, emerge as a compelling dark matter (DM) candidate across a…
