Constraining the Secluded and Catalyzed Annihilation Dark Matter with Fermi-LAT and Planck Data
Yu-Hang Su, Chengfeng Cai, Hong-Hao Zhang
We propose a dark matter (DM) model with a complex scalar charged under a hidden gauge symmetry, denoted as . The scalar field is the DM candidate while the gauge…
General Discussions on the SU(2) Vector Boson Dark Matter Model with a Single Higgs Multiplet -- Lagrangian, Discrete Subgroups, and Scalar Classifications
Chun-Xue Yuan, Zhao Zhang, Chengfeng Cai +2
The vector boson dark matter particles which stem from some broken gauge symmetries usually requires some unbroken symmetries to keep themselves stable. In the previous literature,…
Complex scalar dark matter in a new gauged U(1) symmetry with kinetic and direct mixings
Yu-Hang Su, Chengfeng Cai, Yu-Pan Zeng +1
We propose a scalar dark matter model featuring a hidden gauge symmetry, denoted as U(1)_X, with two complex scalars, Phi and S. In this framework, Phi spontaneously breaks the U(1…
Dark matter phenomenology and phase transition dynamics of the next to minimal composite Higgs model with dilaton
Borui Zhang, Zhao Zhang, Chengfeng Cai +1
In this paper, we conduct a comprehensive study of the Next-to-Minimal Composite Higgs Model (NMCHM) extended with a dilaton field (denoted as NMCHM). A pseudo-Nambu-Gold…
