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…

Leptogenesis and Dark Matter from Low Scale Seesaw

Ang Liu, Zhi-Long Han, Yi Jin +1

In this paper, we perform a detail analysis on leptogenesis and dark matter form low scale seesaw. In the framework of 2HDM, we further introduce one scalar singlet and one…
