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 $S$ and heavy neutral lepton $N$ are further introduced. The Majorana mass term of…

Seesaw Portal to Super Heavy Dark Matter with $Z_{3}$ Symmetry

Cai-Xia Yang, Zhi-Long Han, Fei Huang +2

Right-handed neutrinos $N$ are introduced to explain the origin of the tiny neutrino masses via the seesaw mechanism. Required by relatively large Yukawa coupling and leptogenesis,…

Prospects of $Z^{'}$ Portal Dark Matter in $U (1)_{L_{I^} ¼ - L_{I ¨} }$

Zhen-Wei Wang, Zhi-Long Han, Fei Huang +2

The gauged $U (1)_{L_{I^} ¼ - L_{I ¨} }$ model is well-motivated to explain the muon $g - 2$ anomaly and dark matter in previous studies. However, the latest NA64 $I^¼$ experiment has almost excl…
