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…

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…
