Higgs boson emerging from the dark
Chengfeng Cai, Hong-Hao Zhang, Giacomo Cacciapaglia +2
We propose a new non-thermal mechanism of dark matter production based on vacuum misalignment. A global -charge asymmetry is generated at high temperatures, under which both the…
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…
Minimal asymptotically safe dark matter
Chengfeng Cai, Hong-Hao Zhang
We study a simple class of dark matter models with N_f copies of electroweak fermionic multiplets, stabilized by O(N_F) global symmetry. Unlike conventional minimal dark matter whi…
