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…
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…
Transverse momentum dependence of ratio in high energy collisions
Hai-hong Li, Jun Song, Feng-lan Shao
We apply a constituent quark equal-velocity combination model to study the dependence of ratio in , -Pb and Pb-Pb collisions at LHC energies. We demonstrate…
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 sma…
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…
Conversion-Driven Dark Matter in
Jing-Jing Zhang, Zhi-Long Han, Ang Liu +1
The new gauge boson in is widely considered as the mediator of dark matter. In this paper, we propose the conversion-driven dark matter in . The dark…
