Vector dark matter from split SU(2) gauge bosons
Zexi Hu, Chengfeng Cai, Yi-Lei Tang +2
We propose a vector dark matter model with an exotic dark SU(2) gauge group. Two Higgs triplets are introduced to spontaneously break the symmetry. All of the dark gauge bosons bec…
Inert sextuplet scalar dark matter at the LHC and future colliders
Dan-Yang Liu, Chengfeng Cai, Zhao-Huan Yu +2
We study a dark matter model constructed by extending the standard model with an inert sextuplet scalar of hypercharge 1/2. The sextuplet components are…
Leptogenesis due to oscillating Higgs field
Seishi Enomoto, Chengfeng Cai, Zhao-Huan Yu +1
We propose a new leptogenesis scenario in which the lepton asymmetry and matter particles are simultaneously generated due to the coherent oscillating Higgs background. To demonstr…
Fermionic and scalar dark matter with hidden gauge interaction and kinetic mixing
Juebin Lao, Chengfeng Cai, Zhao-Huan Yu +2
We explore the Dirac fermionic and complex scalar dark matter in the framework of a hidden gauge theory with kinetic mixing between the $\mathrm{U}(1)_\m…
Probing quadruplet scalar dark matter at current and future colliders
Yu-Pan Zeng, Chengfeng Cai, Dan-Yang Liu +2
We investigate a dark matter model involving an inert quadruplet scalar with hypercharge 1/2. After the electroweak symmetry breaking, the dark sector c…
Pseudo-Nambu-Goldstone dark matter and two-Higgs-doublet models
Xue-Min Jiang, Chengfeng Cai, Zhao-Huan Yu +2
We study a dark matter model with one singlet complex scalar and two Higgs doublets. The scalar potential respects a softly broken global symmetry, which makes the imaginary part o…
