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…
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…
Common Origin of Dark Matter and Leptogenesis in
Ang Liu, Feng-Lan Shao, Zhi-Long Han +2
In this paper, we investigate the common parameter space of dark matter and leptogenesis in the symmetry. This model involves a complex scalar , sterile neutrinos $…
Displaced Heavy Neutral Lepton from New Higgs Doublet
Fa-Xin Yang, Feng-Lan Shao, Zhi-Long Han +2
Heavy neutral leptons are introduced to explain the tiny neutrino masses via the seesaw mechanism. For proper small mixing parameter , the heavy neutral leptons …
Probing Dirac Neutrino Properties with Dilepton Signature
Wan-Lun Xu, Zhi-Long Han, Yi Jin +3
The neutrinophilic two Higgs doublet model is one of the simplest models to explain the origin of tiny Dirac neutrino masses. This model introduces a new Higgs doublet with eV scal…
Sterile Neutrino Portal Dark Matter from Semi-Production
Ang Liu, Feng-Lan Shao, Zhi-Long Han +2
In this paper, we study the feeble sterile neutrino portal dark matter under the symmetry. The dark sector consists of one fermion singlet and one scalar singlet , whi…
Sterile Neutrino Portal Dark Matter with Symmetry
An Liu, Zhi-Long Han, Yi Jin +1
In this paper, we consider the sterile neutrino portal dark matter with symmetry. This model further extends the canonical type-I seesaw with a fermion singlet and a scal…
Investigating the gauge boson at the future lepton colliders
Xinyue Yin, Honglei Li, Yi Jin +2
boson as a new gauge boson has been proposed in many new physics models. The interactions of coupling to fermions are detailed studied at the large hadron col…
Same-Sign Tetralepton Signature in Type-II Seesaw at Lepton Colliders
Xu-Hong Bai, Zhi-Long Han, Yi Jin +2
The same-sign tetralepton signature via mixing of neutral Higgs bosons and their cascade decays to charged Higgs bosons is a unique signal in the type-II seesaw model. In this pape…
