Fermionic and scalar dark matter with hidden $\mathrm{U}(1)$ 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 $\mathrm{U}(1{)}_{\mathrm{X}}$ gauge theory with kinetic mixing between the $\mathrm{U}(1)_\m…
