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…
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…
