Portal Dark Matter with Observable
Ang Liu, Zhi-Long Han, Fei Huang
In the conventional portal dark matter scenario, the prediction of detectable dark matter typically relies on the collider sensitivities of and direct de…
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…
Reviving Portal Dark Matter with Conversion Mechanism
Zhen-Wei Wang, Zhi-Long Han, Fei Huang +2
In many new physics models with extended gauge symmetry, the new gauge boson could mediate the interactions between the dark matter and standard model particles. For the conve…
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…
Novel Signatures of Heavy Neutral Lepton at Muon Collider
Xue-Xin Zhang, Zhi-Long Han, Fei Huang +1
The Higgs-strahlung process is one of the most important production channels of the standard model Higgs boson at the lepton colliders. The cross section…
