New Avenues of Heavy Neutral Lepton at Muon Collider
Fa-Xin Yang, Feng-Lan Shao, Zhi-Long Han +1
With initial state radiation, the multi-TeV muon collider can be regarded as an electroweak boson collider. The dominant production mode of the certain process becomes the vector b…
Same-Sign Tetralepton Signature at TRISTAN
Lin-Kun Yan, Zhi-Long Han, Feng-Lan Shao +1
Naturally tiny neutrino masses can be explained by the low scale seesaw with heavy neutral lepton coupling to the neutrinophilic Higgs doublet , which obtains a much small…
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…
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 …
Heavy Neutral Leptons in Gauged at Muon Collider
Ru-Yi He, Jia-Qi Huang, Jin-Yuan Xu +3
Heavy neutral leptons are the most appealing candidates to generate the tiny neutrino masses. In this paper, we study the signature of heavy neutral leptons in gauged $U(1)_{L_…
Same-Sign Dilepton Signature in the Inert Doublet Model
Fa-Xin Yang, Zhi-Long Han, Yi Jin
In this paper, we perform a detailed analysis on the same-sign dilepton signature in the inert doublet model. Focusing on the low dark matter mass region, we randomly scan the corr…
