Collider Probes of Four-Lepton Final States in Maximally Flavor-Violating Model
Jianing Qin, Fei Huang, Honglei Li +2
We investigate the collider signatures of the maximally flavor-violating model, where a new gauge boson and scalar triplets induce lepton flavor-changin…
Reviving Portal Dark Matter with Conversion Mechanism
Zhen-Wei Wang, Zhi-Long Han, Fei Huang +2
In many new physics models with extended gauge symmetry, the new gauge boson could mediate the interactions between the dark matter and standard model particles. For the conve…
Coscattering Dark Matter in the Inverse Scotogenic Models
Ang Liu, Zhi-Long Han, Fei Huang +2
The Scotogenic mechanism is an appealing pathway to naturally explain the common origin of dark matter and tiny neutrino mass. However, the conventional scotogenic dark matter usua…
Seesaw Portal to Super Heavy Dark Matter with Symmetry
Cai-Xia Yang, Zhi-Long Han, Fei Huang +2
Right-handed neutrinos are introduced to explain the origin of the tiny neutrino masses via the seesaw mechanism. Required by relatively large Yukawa coupling and leptogenesis,…
Lepton Number Violation Higgs Decay at Muon Collider
Fa-Xin Yang, Feng-Lan Shao, Zhi-Long Han +3
In this paper, we consider the scalar singlet extension of type-I seesaw, where a scalar singlet and heavy neutral lepton are further introduced. The Majorana mass term of…
Prospects of Portal Dark Matter in
Zhen-Wei Wang, Zhi-Long Han, Fei Huang +2
The gauged model is well-motivated to explain the muon anomaly and dark matter in previous studies. However, the latest NA64 experiment has almost exclude…
