A New Probe for Long-Lived Particles at Higgs Factories: Displaced Photons in the Hadronic Calorimeter
Zhicheng Jiang, Hengne Li, Jin-Han Liang
The search for dark matter and other photon-portal long-lived particles (LLPs) at electron-positron colliders often relies on the mono-photon signature. At future Higgs factories o…

Probing lepton flavor violating dark matter scenarios via astrophysical photons and positrons
Jin-Han Liang, Yi Liao, Xiao-Dong Ma
In this Letter we explore, for the first time, the constraints on lepton flavor violating (LFV) dark matter (DM) scenarios via the astrophysical photons and positrons, including bo…

A systematic investigation on vector dark matter-nucleus scattering in effective field theories
Jin-Han Liang, Yi Liao, Xiao-Dong Ma +1
In this paper, we systematically investigate the general spin-one dark matter-nucleus interactions within the framework of effective field theories (EFT). We consider both the nonr…
