Portal Dark Matter with Observable
Ang Liu, Zhi-Long Han, Fei Huang
In the conventional portal dark matter scenario, the prediction of detectable dark matter typically relies on the collider sensitivities of and direct det…
Novel Signatures of Heavy Neutral Lepton at Muon Collider
Xue-Xin Zhang, Zhi-Long Han, Fei Huang +1
The Higgs-strahlung process is one of the most important production channels of the standard model Higgs boson at the lepton colliders. The cross section…
Study the property of at future collider
Xinyi Yan, Honglei Li, Zhi-Long Han +2
As a strong candidate for new physics beyond the Standard Model, the exotic charged gauge boson has attracted extensive research interest. In this work we investigate…
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…
Research of Extra Charged Gauge Boson in Alternative Left-Right Model at Future Muon Collider
Liuxin Zhao, Honglei Li, Zhi-Long Han +2
The study of extra charged gauge boson beyond the Standard Model has always been of great interest. Future muon colliders will have a significant advantage in discovering exotic pa…
Single Production of Doubly Charged Higgs at Muon Collider
Jie-Cheng Jia, Zhi-Long Han, Fei Huang +2
In this paper, we study the single production of doubly charged Higgs in the type-II seesaw at the high energy muon collider. Compared with the pair production channel…
Phenomenological study of heavy neutral gauge boson in the left-right symmetric model at future muon collider
Zongyang Lu, Jianing Qin, Honglei Li +5
The exotic neutral gauge boson is a powerful candidate for the new physics beyond the standard model. As a promising model, the left-right symmetric model has been proposed to expl…
